| HMC712LP3CE v01.0309 GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, 5 - 26.5 GHz 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 5 ATTENUATORS - ANALOG - SMT Typical Applications The HMC712LP3CE is ideal for: * Point-to-Point Radio * VSAT Radio * Test Instrumentation * Microwave Sensors * Military, ECM & Radar 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 voltage of the 2nd attenuation stage, Vctrl2, should then be varied from -3V to 0V, with Vctrl1 fixed at 0V. The HMC712LP3CE is housed in a RoHS compliant 3x3 mm QFN leadless package However, if the Vctrl1 and Vctrl2 pins are connected together it is possible to achieve the full analog attenuation range with only a small degradation in input IP3 performance. Applications include AGC circuits and temperature compensation of multiple gain stages in microwave point-to-point and VSAT radios.
