    Qorvo's TQM879008 is a digital variable gain amplifier (DVGA) featuring high linearity over the entire gain control range. This amplifier module integrates two gain blocks, a digital-step attenuator (DSA) and a high linearity 0.5 W amplifier. The module has the added feature of integrating all matching components, bias chokes and blocking capacitors. 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 (SPI™).

    The TQM879008 features variable gain from 10 dB to 41.5 dB at 2.5 GHz, +48.5 dBm output IP3, and +27.3 dBm P1dB. The module operates from a single +5 V supply and is available in a compact 28-pin 6 x 6 mm leadless SMT package.

    The TQM879008 is pin compatible with the TQM829007 (0.7 - 1.0 GHz, 0.25 W DVGA) and TQM879006 (1.8 - 2.7 GHz, 0.25 W DVGA). This allows one to size the right type of device for specific system level requirements as well as making the DVGA family ideal for applications where a common PCB layout is used for different frequency bands.
