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 TQM8M9077 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 TQM8M9077 is packaged in a RoHS-compliant, compact 5x5 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 +85º C.

This serial control interface converts the serial data input stream to parallel output word. The input is 3-wire (CLK, LE and SERIN) SPITM input compatible. At power up, the serial control interface resets the DSA to the minimum gain state. The 6-bit SERIN word is loaded into the register on rising edge of the CLK, MSB first. When LE is high, CLK is disabled.
