This amplifier module integrates a gain block, a digital-step attenuator (DSA), and a high linearity ½ Watt amplifier into a compact 4 x 4 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 serial periphery interface (SPITM). 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 5 V supply. The module is available in a compact 24-pin 4 x 4 mm leadless SMT package.
