General Description

Pin Configuration

The TQM879026 is a digital variable gain amplifier

(DVGA) featuring high linearity and digital variable gain

control in 0.5 dB step sizes. This DVGA integrates a

gain block, a digital-step attenuator (DSA), and a high

linearity ¼-watt amplifier into a compact 4x4 mm

package. The internal 6-bit DSA provides a 31.5 dB

gain control range and is controlled with a serial

periphery interface (SPI^TM). The individual stages are

accessible to external ports to allow for optimization of

the last stage amplifier for individual bands and also

allowing other functional blocks to be added in-

between the stages.

The TQM879026 features variable gain from 1 dB to

32 dB at 2.14 GHz, +42.5 dBm output IP3, and +24

dBm P1dB while only consuming 176 mA current from

a 5V supply. The module is available in a compact 24-

pin 4x4 mm leadless SMT package.
