General Description

Pin Configuration

The TQM8M9075 is a digitally controlled variable gain

amplifier (DVGA) with a broadband frequency range of

50 to 4000 MHz. The DVGA features high linearity and

low noise while providing digital variable gain with a

31.5 dB of range in 0.5 dB steps through a 6-bit serial

mode control interface.

This combination of

5, 6, 7, 8, 9, 10

performance parameters makes the DVGA ideal for

receiver applications requiring gain control with high

IIP3 and low noise figure.

The TQM8M9075 integrates a high performance digital

step attenuator and a high linearity, broadband gain

block. Both stages are internally matched to 50 Ohms

and do not require any external matching components.

A serial output port enables cascading with other serial

controlled devices.

The TQM8M9075 is packaged in a RoHS-compliant,

compact 5x5 mm surface-mount leadless package.

Superior thermal design allows the product to have a

minimum MTTF rating of 1000 years at a mounting

temperature of +85°C.
