This DVGA integrates a gain block, a digital-step attenuator (DSA), and a high linearity ¼-watt amplifier into a compact 4x4 mm package. The internal 6-bit DSA provides a 3.5 db gain control range and is controlled with a serial periphery interface (SPI TM ). The individual stages are accessible to external ports to allow for optimization of the last stage amplifier for individual bands and also allowing other functional blocks to be added in-between the stages. The features variable gain from db to 3 db at.4 GHz, +4.5 dbm output IP3, and +4 dbm PdB while only consuming 74 ma current from a 5V supply. The module is available in a compact 4-pin 4x4 mm leadless SMT package.

3 Serial Control Interface The has a CMOS SPI TM input compatible serial interface. This serial control interface converts the serial data input stream to parallel output word. The input is 3-wire (CLK, LE and SID) SPI TM input compatible. At power up, the serial control interface resets the DSA to the minimum gain state. The 6-bit SID (Serial Input Data) word is loaded into the register on rising edge of the CLK, MSB first. When LE is high, CLK is internally disabled.

14 Detailed Device Description The is a digital variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. The amplifier module features the integration of a 5 Ω internally matched high linearity low noise amplifier gain block, a digital step attenuator (DSA), along with a high linearity ¼W amplifier as shown in the functional diagram below. The DVGA has an operational frequency range from.7 4. GHz. The three stages are individually accessible via package I/O contacts. This permits full flexibility to insert other components or filters between the stages. Functional Schematic Diagram AMP DSA AMP SPI AMP AMP is a high linearity low noise amplifier. The amplifier has high gain across a broad range of frequencies while also providing very low noise. It is internally matched and only requires an external choke and blocking/bypass capacitors for operation from a single +5V supply. The internal active bias circuit also enables stable operation over bias and temperature variations. At.9 GHz, the amplifier typically provides 9.8 db gain, +36 dbm OIP3, and.3 db Noise Figure while only drawing 85 ma of current. DSA (Digital Step Attenuator) The DSA is a high linearity, low insertion loss, 6-bit, 3.5 db Digital Step Attenuator (DSA) operating over the 7-4 MHz frequency range. The digital step attenuator uses a single positive 5V supply and has a serial periphery interface (SPI TM ) for changing attenuation states. This product maintains high attenuation accuracy over frequency and temperature. No external matching components are needed for the DSA. AMP AMP is a high-linearity driver amplifier that delivers high performance past 4GHz. With external tuning it can achieve over +4 dbm OIP3 with +5 dbm PdB while only consuming 87 ma of quiescent current.
