    Qorvo's TQM8M9076 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. The TQM8M9076 integrates a high performance digital step attenuator followed by a high linearity, broadband gain block. The input and output of the individual stages are accessible with external pins to allow for optimization of performance at any sub-band across the DVGA's 0.05 to 4.0 GHz operating frequency range.

    The part 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 TQM8M9076 is targeted for use in wireless infrastructure, point-to-point or can be used for any general purpose wireless application.
