General Description
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.
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.
The TQC9074 is targeted for use in wireless
infrastructure where high linearity, medium power, and
high efficiency are required.
