HMC712LP3C v06.0312 ATTENUATOR - ANALOG - SMT GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, 5 - 26.5 GHz Typical Applications Features The HMC712LP3CE is ideal for: Wide Bandwidth: 5 - 26.5 GHz * Point-to-Point Radio Excellent Linearity: +28 dBm Input P1dB * VSAT Radio Wide Attenuation Range: 28 dB * Test Instrumentation Absorptive Topology * Microwave Sensors Singe or Dual Control Operation * Military, ECM & Radar 16 Lead 3x3mm SMT Package: 9mm 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. Electrical Specifications, TA = +25 C, 50 Ohm system Parameter Typ.
