General Description
The 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 ½ 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 （SPITM）。
The TQM879008 features variable gain from 10 dB to 41.1dB at 2.5 GHz， +47.5 dBm output IP3， and +27.3 dBm P1dB. The module operates from a single +5V supply and is available in a compact 28-pin 6x6 mm leadless SMT package.
The TQM879008 is pin compatible with the TQM829007 （0.7-1.0GHz， 0.25W DVGA） and TQM879006 （1.4- 2.7GHz， 0.25W 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.
