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 (SPI^TM).
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.
The TQM879006A is pin compatible with the
TQM829007 (0.6-1GHz, 0.25W DVGA) and TQM879008
(1.5-2.7 GHz, 0.5W 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.
