This amplifier module integrates a gain block, a digital-step attenuator (DSA), and a high linearity ½ Watt amplifier into a compact 4x4 mm module. The internal 6-bit DSA provides a 31.5 dB gain control range in 0.5 dB steps, and is controlled with a TM serial periphery interface (SPI ). 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 TQM879028 features variable gain from 0.5 dB to 32 dB at 2.14 GHz, +44 dBm output IP3, and +27.5 dBm P1dB while only consuming 230 mA current from a 5V supply. The module is available in a compact 24-pin 4x4 mm leadless SMT package.

This serial control interface converts the serial TM data input stream to parallel output word. The input is 3-wire (CLK, LE and SID) SPI 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.
