TQM8M9076 0.05 - 4 GHz Digital Variable Gain Amplifier Applications Wireless Infrastructure Fixed Wireless Microwave and Satellite Radio IF and RF Applications General Purpose Wireless 32 Pin 5 x 5 mm Leadless SMT Package 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. Datasheet Rev.

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