General Description

Amp1_In

The TQC9074 is a high dynamic range analog controlled

variable gain amplifier (VGA) which operates from 0.7 to

2.8 GHz. The VGA is able to achieve high performance

with +42.0 dBm OIP3 and +27.1 dBm P1dB over a wide

gain variation range while only consuming 235 mA

current.

RF/DC Ground

The TQC9074 integrates a high linearity, low noise

amplifier for the first stage, followed by a broadband

voltage variable attenuator, and then with a high

performance ½W P1dB amplifier. The input and output

of the various individual stages are accessible with

external pins to allow for optimization of performance at

any sub-band across the VGA’s 0.7 to 2.8 GHz

operating frequency range. The TQC9074 is packaged

in a RoHS-compliant, compact 5x5mm surface-mount

leadless package. Superior thermal design allows the

product to have a minimum MTTF rating of 1000 years

at a mounting temperature of +85º C.
