6 Attenuation Band Reject Filter Bandpass Filter Glossary Loss of signal in transmission through a filter, usually referring signal amplitude or signal power. Generally measured in decibels (db). A filter that rejects one band of frequencies and passes both higher and lower frequencies. Sometimes called a notch filter. A filter that passes one band of frequencies and rejects both higher and lower frequencies. Bandwidth The width of the passband of a bandpass filter. Usually expressed as the frequency difference between lower and upper 3dB relative points. Bessel Function Butterworth Function enter Frequency (Fc) A mathematical function used yield a maximally constant time delay in a filter with no consideration for amplitude response. This function is very close a Gaussian function. A mathematical function used yield a maximally constant amplitude response in a filter with no consideration for time delay, or phase response. The arithmetic mean frequency normally calculated using the 3dB relative band edges (F1 & F2). Fc = (F1 + F2)/2 Where F1 and F2 are lower and upper frequencies respectively at which a particular signal attenuation occurs, usually taken as 3dB relative attenuation. An important parameter of bandpass and bandsp filters. ut-off Frequency (Fco) Decibel (db) The upper passband edge in lowpass filters or the lower passband edge in highpass filters. The passband edge closest the sp band. Filtek normally uses the point at which the VSWR equals 1.:1. A unit used express the ratio between two amounts of power P1 and P2 existing at two points. By definition: db = 10 LOG 10 (P1/P2) It can also be used express voltage and current ratios but only when the voltage or current is measured at places having identical impedance. Dissipation Disrtion Elliptic Function Energy losses in a filter due resistive or core losses. Generally speaking, the modification of signals which produce an undesirable end effect. These modifications can relate phase, amplitude, delay, etc. The disrtion of a sine wave is usually defined as the percentage of signal power remaining after the fundamental sine wave component has been removed. A mathematical function used yield the squarest possible amplitude filter response with a given number of circuit elements. The elliptic function has a Tchebycheff response in both the passband and the spband. The elliptic function filter has a poorer phase response and transient response than any of the classical transfer functions.

7 Envelope Delay Highpass Filter Input Impedance Insertion Loss Linear Phase Filter Load Impedance Lowpass Filter Overshoot Passband Passband Ripple Phase Shift Q The propagation time delay of the envelope of an amplitude modulated signal as it passes through a filter. Sometimes called time delay or group delay. Envelope delay is proportional the slope of the phase shift response versus frequency curve. Envelope delay disrtion occurs when the delay is not constant at all frequencies in the passband area. A filter which passes high frequencies and rejects low frequencies. The impedance measured at the input terminal of a filter when it is properly terminated at its output. The loss of signal caused by a filter being inserted in a circuit. It can be expressed in many forms and is usually measured in db. In general, it is the ratio of voltage delivered the load (at peak frequency response) with the filter in the circuit, the voltage in the load if a perfect lossless matching transformer replaced the filter. When a filter is inserted between two circuits whose impedance differs widely, it is sometimes more practical specify insertion loss by some other method. A filter that exhibits a constant change in degrees per unit of frequency. The resultant plot of frequency vs. phase is a straight line. This type of filter ideally displays a constant delay in its passband. The impedance that normally must be connected the output terminal of the filter in order meet filter specifications; The filter output will drive this load. A filter which passes low frequencies and rejects high frequencies. The amount in percent by which a signal exceeds its steady-state output on its initial rise. The frequency range passed by a filter. Variations of attenuation with frequency within the passband of a filter. The changing of phase of a signal as it passes through a filter. A delay in time of the signal is referred as phase lag and in normal networks, phase lag increases with frequency, producing a positive envelope delay (see envelope delay). The figure of merit of a capacir or inducr. The ratio of its reactance its equivalent series resistance. Also in bandpass filters loaded Q is a term used define the percentage of 3 db bandwidth. Loaded Q = enter Frequency (Fc) / 3 db Bandwidth Relative Attenuation Return Loss Attenuation measured with the point of minimum attenuation taken as zero db, or: (Relative Attenuation = Attenuation minus Insertion Loss.) The ratio in db of maximum power sent down a transmission line the power returned ward the source. Also equal times the log of the reciprocal of the reflection coefficient. If return loss is infinite, all power is absorbed in the circuit. 6

8 Ringing Ripple Rise Time Shape Facr The tendency of a filter oscillate for a time when a transient waveform is applied it. Generally referring the wavelike variations in the amplitude response of a filter. Tchebycheff and elliptic function filters ideally have equi-ripple characteristics, which means that the difference in peaks and valleys of the amplitude response in the passband are always the same. Butterworth, Gaussian, and Bessel functions have no ripple. Ripple is usually measured in db. The length of time it takes a step-function at the output of a filter move from 10% 90% of its steady state value on the initial rise. An important parameter of all filters: Bandpass: Bandsp: Lowpass: Highpass: SF = Attenuation Bandwidth/ 3 db Bandwidth SF = 3 db Bandwidth/ Attenuation Bandwidth SF = Attenuation Frequency / Fco SF = Fco / Attenuation Frequency Source Impedance Step Function Spband Tchebycheff Function Time Delay Transient Response Voltage Standing Wave Ratio (VSWR) The output impedance of the circuit that drives the filter. The impedance of the circuit the filter must work from or be tested in. A signal change in amplitude from one level another which occurs in zero time. Usually refers a rectangular front waveform used in testing transient response. The area of frequency where it is desirable reject or attenuate all signals as much as practical. A mathematical function that produces a curve that defines ripples within certain bounds (see ripple). This function produces a squarer amplitude response than the Butterworth function but with less desirable phase, and time delay characteristics. There is a whole family of Tchebycheff functions (0.1 ripple, 0. ripple, etc.). The amount of time it takes for certain signals pass through a filter. The response of a lowpass filter a step function, or very low frequency square wave. If a sudden voltage rise is applied a lowpass filter the output will respond some time later. Transient response can also apply a bandpass filter responding a sudden burst of signal within its passband. The ratio between the peak and valley of standing waves on a transmission time. 7

9 General Performance enter Frequency Insertion Loss (db) db Relative Bandwidth 2 Section 4 6 Section % of 3 db Bandwidth (Typical) It is often advantageous know more about the passband of a filter than its center frequency loss and its 3 db bandwidths. The graphs on this page show the approximate relationships of the 0., 1.0 and 2.0 db relative bandwidths the 3 db relative bandwidth. They also serve illustrate how the number of sections and the insertion loss affect these relationships. enter Frequency Insertion Loss (db) db Relative Bandwidth 2 Section 4 6 Section % of 3 db Bandwidth (Typical) enter Frequency Insertion Loss (db) db Relative Bandwidth 2 Section % of 3 db Bandwidth (Typical) 4 6 Section 8

10 General Performance.0 Relative Phase Bandwidth phase bandwidth vs. 3 db bandwidth: This graph should serve as a general guide for filter requirements regarding phase linearity. As an example, a four section filter with an insertion loss of 3.0 db at center frequency should exhibit ± linearity over % of the bandwidth. enter Frequency Insertion Loss (db) Section 4 6 Section % of 3 db Bandwidth (Typical) 3 db% Bandwidth Facr Since the 3 db bandwidth is a minimum bandwidth, the typical maximum bandwidth may be of some concern. This graph defines the typical variation incurred in the manufacturing process. For example, in a bandpass filter: enter Frequency = 100 MHz 3 db Bandwidth = MHz 3 db % Bandwidth = % From the chart at %, the facr = 1.10, therefore the 3 db relative bandwidth could vary from MHz 33 MHz. 9

It also serves illustrate how the number of sections and the insertion loss affect these relationships. Diplexers and Multiplexers Filters within any of the bandpass series or combinations of different series may be used form the basic networks of diplexers or multiplexers. One terminal of each filter network is common the assembly, the other terminals remain separate and are isolated from each other. Thus signals applied the common terminal are separated in accordance with the passband frequencies of the filter networks; Signals applied the isolated terminals are combined at the common terminal. The passband of the individual network may be contiguous or separated by overlapping spbands. For information regarding your specific applications contact Filtek. Insertion Loss Frequency 10

37 Spband Attenuation The graphs on the following pages define the normal specification limits of attenuation for FILTEK ombline and Interdigital Bandpass filters. The minimum level of attenuation in db is shown as a "Number of 3dB Bandwidths from enter Frequency." Since the filter characteristics vary for differing bandwidths, it is necessary establish specifications for each bandwidth of filter. The different graphs represent the various 3dB percentage bandwidths. The 3dB percentage bandwidth is defined as follows: The exact relationship is as follows: 3dB Bandwidth (MHz) x 100 enter Frequency (MHz) 1. 3dB bandwidths from center frequency = Rejection Frequency (MHz) - enter Frequency (MHz) 3dB Bandwidth (MHz) 2. enter Frequency = 00 MHz Minimum 3 db Bandwidth = 0 MHz Number of sections = Find: Minimum attenuation levels at 42 MHz and 800 MHz. ombline and Interdigital Bandpass 3 db bandwidths from Fc = (42-00) / 0 = - 1. and (800-00) / = As the three db Bandwidth is exactly 10% of the center frequency, the answer can be read directly from the 10% graph.
