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.
