TQM8M9074
700 - 2800 MHz Analog Controlled Variable Gain Amplifier
Qorvo's TQM8M9074 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 +43 dBm OIP3 and +27.5 dBm P1dB over a wide gain variation range while only consuming 225 mA current.
The part integrates a high linearity, low noise amplifier for the first stage, followed by a broadband voltage variable attenuator and then with a high performance 0.5 Watt 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 TQM8M9074 is packaged in a RoHS compliant, compact 5 x 5 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.
The TQM8M9074 is targeted for use in wireless infrastructure where high linearity, medium power and high efficiency are required.
