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