　　General Description

　　The 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 31.5?dB of range in 0.5?dB steps through a 6-bit serial mode control interface. This combination of performance parameters makes the DVGA ideal for receiver applications requiring gain control with high IIP3 and low noise figure. The TQM8M9076 integrates a high performance digital step attenuator and a high linearity， broadband gain block. Both stages are internally matched to 50?Ohms and do not require any external matching components. A serial output port enables cascading with other serial controlled devices. The TQM8M9076 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.
