TQM879028
600 - 4000 MHz, 0.5 Watt Serial Controlled Digital Variable Gain Amplifier, 6-Bit, 0.5 dB Steps, Packaged
Qorvo's TQM879028 is a digital variable gain amplifier (DVGA) featuring high linearity performance in a fully integrated module. The amplifier module features the integration of a high performance gain block, a digital step attenuator (DSA), along with a high linearity 1/2 W amplifier in a compact package. The internal DSA offers 0.5 dB step, 6-bit, and 31.5 dB range and has a serial controlled interface. 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 1.5 dB to 33 dB at 2.14 GHz, +45 dBm output IP3, and +27 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.
