HMC712LP3C

v06.0312 HMC712LP3C GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, 5 - 26.5 GHz ATTENUATOR - ANALOG - SMT Typical Applications The HMC712LP3CE is ideal for: Point-to-Point Radio VSAT Radio Test Instrumentation Microwave Sensors Military, ECM & Radar Features Wide Bandwidth: 5 - 26.5 GHz Excellent Linearity: +28 dBm Input P1dB Wide Attenuation Range: 28 dB Absorptive Topology Singe or Dual Control Operation 16 Lead 3x3mm SMT Package: 9mm² Functional Diagram General Description The HMC712LP3CE is an absorptive Voltage Variable Attenuator (VVA) which operates from 5 - 26.5 GHz and is ideal in designs where an analog DC control signal must be used to control RF signal levels over a 28 dB amplitude range. It features two shunt-type attenuators which are controlled by two analog voltages, Vctrl1 and Vctrl2. Optimum linearity performance of the attenuator is achieved by first varying Vctrl1 of the 1st attenuation stage from -3V to 0V with Vctrl2 fixed at -3V. The control v...
