Digital Variable Gain Amplifier
The TriQuint TQM8M9077 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. This combination of performance parameters makes the DVGA ideal for receiver applications requiring gain control with high IIP3.
The part 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 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 +85ยบ C.
The TQM8M9077 is targeted for use in wireless infrastructure, point-to-point or can be used for any general purpose wireless application.
