TQM8M9075 0.05-4 GHz Digital Variable Gain Amplifier Applications Wireless Infrastructure Fixed Wireless Microwave and Satellite Radio General Purpose Wireless 32-pin 5x5mm leadless SMT package Product Features Integrates DSA + Amp Functionality 50-4000 MHz Broadband Performance 18 dB Gain @ 2.14 GHz 2.9 dB Noise Figure @ max gain setting +21 dBm P1dB +36.5 dBm OIP3 +5 V Supply Voltage 88 mA Operating Current MTTF > 1000 Years Functional Block Diagram General Description 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. 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 +85º C. The TQM8M9075 is targeted for use in wireless infrastructure, p...
