General Description

The TQC9312 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 (SPI^TM).

The TQC9312 features variable gain from 9 dB to 40dB

at 3.5 GHz, +44.5 dBm output IP3, and +27.8 dBm

P1dB. The module operates from a single +5V supply

and is available in a compact 28-pin 6x6 mm leadless

SMT package.

The TQC9312 is pin compatible with the TQM879008

(1.5-2.7GHz, 0.5W P1dB) and TQM879006A (1.4-

2.7GHz, 0.25W P1dB). 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.
