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 TQM8M9076 is packaged in a RoHS-compliant, compact 5x5 mm surface-mount leadless package. Superior thermal design allows the product to ha...
