TQM8M9075 0.05−4 GHz Digital Variable Gain Amplifier Applications Wireless Infrastructure Fixed Wireless Microwave and Satellite Radio General Purpose Wireless 5x5mm 32-pin leadless SMT package The TQM8M9075 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 TQM8M9075 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 +85°C. The TQM8M9075 is targeted for use in wireless infrastructure, point-to-point, or can be used for any general purpose wireless application. © 2012 TriQuint Semiconductor, Inc. 25 CLK 26 SID 27 LE 28 GND 29 AMPout/VAMP 1 24 NC GND 2 23 NC GND 3 22 NC ATTout 4 ACG1 5 ACG2 6 19 NC ACG3 7 18 NC ACG4 8 17 VDD 21 NC 20 NC NC 16 NC 15 GND 13 ATTin 12 SOD 14 6-BIT SPI DSA Pin Configuration The TQM8M9075 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 and low noise figure.

This serial control interface converts the TM serial data input stream to parallel output word. The input is 3-wire (CLK, LE and SID) SPI 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.
