ATTENUATORS - SMT PRELIMINARY 8 Typical Applications The HMC812ALC4 is ideal for: Point-to-Point Radio VSAT Radio Test Instrumentation Microwave Sensors Military, ECM & Radar Functional Diagram HMC812ALC4 v06.1216 GaAs MMIC VOLTAGE-VARIABLE ATTENUATOR, 5 - 30 GHz Features Wide Bandwidth: 5 - 30 GHz Excellent Linearity: +32 dBm Input IP3 High Power Handling: +25 dBm Input P1dB Wide Attenuation Range: 30 dB 24 Lead Ceramic 4x4 mm SMT Package: 16mm² General Description The HMC812ALC4 is an absorptive Voltage Variable Attenuator (VVA) which operates from 5 - 30 GHz and is ideal in designs where an analog DC control signal must be used to control RF signal levels over a 30 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 -5V to 0V with Vctrl2 fixed at -5V. The control voltage of ...
