Functional Block Diagram
General Description
The TQM879006A is a digital variable gain amplifier
(DVGA) featuring high linearity over the entire gain
control range. The amplifier module features the
integration of a low noise amplifier gain block, a digital-
step attenuator (DSA), along with a high linearity ¼W
amplifier. The module has the added features of
integrating all matching components with bias chokes
and blocking capacitors. The internal DSA offers 0.5
dB step, 6-bit, and 31.5 dB range and is controlled with
a serial periphery interface (SPITM).
The TQM879006A features variable gain from 0 dB to
31.7 dB at 2 GHz, has +43 dBm Output IP3, and +24.5
dBm P1dB. The amplifier also has a very low 1.5 dB
Noise Figure (at maximum gain) allowing it to be an
ideal DVGA for both receiver and transmitter
applications. The amplifier operates from a single +5V
supply and is available in a compact 28-pin 6x6 mm
leadless SMT package.
