7 LA5, 5M Proper cares in using IC. Bias condition : RF VCC IF VCC. Avoid coupling between the antenna tuning circuit and the local oscillation.. Connect detection capacitor C5 across pins (output) and (VCC) so that no leakage of the IF signal to the GND line occurs. (If connected to GND, the tweet and the usable sensitivity may get worse.) Radiation from C5 may cause harmonics in the IF signal to return to the RF stage, thereby leading to more tweet interference. So, connect C5 as close to pins, as possible. Consider the direction of the capacitor and separate it from the ANT circuit.. For R9, use a semifixed resistor with VSM considered. 5. When designing the coils, consider the following conditions.

8 LA5, 5M 7. Meaning of L If the RF stage is double-tunned, the difference in sensitivity within the RF band almost disappears, but an antireasonance point of approximately MHz appears, thereby leading to worse spurious characteristics. So, L is used to remove the SW band. 8. Wide-band AGC This IC contains -channel wide-band AGC. Pin detects an undesired signal within the RF band and wide-band AGC is applied. This detection sensitivity is determined inside the IC. Pin detects an undesired signal outside the RF band. This detection sensitivity is determined by R. When mvrms (f = MHz) signal is applied to pin, AGC operates. 9. Measures against suppression of sensitivity In the AGC circuit of the test circuit the presence of an undesired signal of high strength within the receiving band may cause the desired signal to be suppressed when the desired signal is low or medium in strength. Shown below is the circuit configuration where the necessary measures are taken against this suppression.

When using LW (approximately 5 C or greater), additionally connect a resistor of 7kΩ across pins 8 and 9 against increase in local oscillation level.

The variations (especially in case of small coupling coefficient) in the oscilation coil may cause a parasitic oscillation of approximately MHz to occur at the local oscillation buffer output (pin ) at low temperatures. In this case, connect a capacitor of pf or greater across pin and GND. (When the oscillation coil is used with no tap, no problem arises.). The recommended double-tuning circuit has a loose coupling at T. Therefore, the change in the total number of turns may affect the coupling coefficient subtly, causing a tight coupling and making the selectivity characteristic double-humped. Especially for a receiving band of khz or more, the tracking method may affect the band characteristic of sensitivity and the cross modulation characteristic considerably. When making a design, check to see if critical coupling occurs or not. 5. Sensitivity difference at khz or less In the application circuit configuration shown below, the bypass capacitor in the position where the tuning voltage is applied and coupling L for double-tuning may cause an antiresonance point of khz to khz depending on the variations in the coil, varactor diode, etc. The value of the bypass must be.7μf or greater.

10 LA5, 5M. Measure against suppression of sensitivity in the presence of an undesired signal of high strength (Sample application where two PIN diodes are used in the antenna damping circuit) The LA5 contains the wide-band AGC circuit (wide-band AGC with pin input) against cross modulation which occurs because an undesired signal of high strength distorts the FET input. The AGC = ON level depends on the value of external resistor R as shown below. 5 W.B.AGC-ON level dbμ Test conditions Ω Double-tuning JIS antd 5Ω SC5 V DD = 8V R SC5 μf 85 f u ANT input level SC9 at which ANTD is turned ON when 8 fu =.MHz is inputed at fr = MHz Resistor value, R Ω When a nonlinear element, such as transistor, is used for antenna damping, cross modulation which occurs when the transistor is turned ON is as shown below..7μf 5Ω kω.μf R μf Output db Desired :.MHz Hz %mod 7dBμ Undesired :.MHz non-mod Ω 5 Desired :.MHz Hz non-mod 7dBμ Undesired :.MHz khz 8%mod Wide-band AGC (pin input)75ω Ω Cross modulation which occurs when the 7 transistor for ANT damping is turned ON Undesired input dbμ 75Ω 5Ω 5Ω pick up R The dynamic range of the FET input covers up to approximately dbμ of antenna input, but the AGC-ON level must be set lower because of the bad effect shown above. Therefore, there are some cases where it is difficult to receive a desired signal of low strength in the presence of an an undesired signal of high strength. To solve this problem, a sample application circuit where two PIN diodes with good linearity are used for antenna damping and its cross modulation characteristic are shown below.
