General Description

Pin Configuration

The TQC9305 is a digitally controlled variable gain

amplifier (DVGA) with a broadband frequency range of

700 to 3600 MHz. The DVGA features high linearity and

low noise while providing digital variable gain with a 31

dB of range in 1 dB steps through a serial mode control

interface. At 1.9 GHz, the DVGA typically provides 13

dB gain, +40 dBm OIP3, +23 dBm P1dB and 3.1 dB

noise figure. This combination of performance

parameters makes the DVGA ideal for receiver

applications requiring gain control with high IIP3 and low

noise figure. In addition, the DVGA integrates a shut-

down biasing capability to allow for easy operation for

TDD applications.

The TQC9305 integrates a high performance digital step

attenuator followed by a high linearity, broadband gain

block. Both stages are internally matched to 50 Ohms

and do not require any external matching components.

The TQC9305 is packaged in a RoHS-compliant,

compact 5x5 mm surface-mount leadless package.
