attenuators - analog - SMT v01.0813 Typical Applications The HMC985LP4KE is ideal for: Point-to-Point Radio VSAT Radio Test Instrumentation Microwave Sensors Military, ECM & Radar Functional Diagram HMC985LP4KE GaAs MMIC VOLTAGE - VARIABLE ATTENUATOR, 10 - 40 GHz Features Wide Bandwidth: 10 - 40 GHz Excellent Linearity: +32 dB Input IP3 Wide Attenuation Range: 35 dB No External Matching 24 Lead 4x4 mm SMT Package: 16 mm² General Description The HMC985LP4KE is an absorptive Voltage Variable Attenuator (VVA) which operates from 10 - 40 GHz and is ideal in designs where an analog DC control signal must be used to control RF signal levels over a 35 dB dynamic range. It features two shunt-type attenuators which are controlled by two analog voltages, Vctl1 and Vctl2. Optimum linearity performance of the attenuator is achieved by first varying Vctl1 of the first attenuation stage from -3V to 0V with Vctl2 fixed at -3V. The control voltage of the second attenuation ...
