The HMC985ALP4KE is an absorptive VoltageVariable Attenuator (VVA) which operates from 10- 40 GHz and is ideal in designs where an analogDC control signal must be used to control RF signallevels over a 35 dB dynamic range. It features twoshunt-type attenuators which are controlled by twoanalog voltages, Vctl1 and Vctl2. Optimum linearityperformance of the attenuator is achieved by firstvarying Vctl1 of the first attenuation stage from -5V to0V with Vctl2 fixed at -5V. The control voltage of thesecond attenuation stage, Vctl2, should then be variedfrom -5V to 0V with Vctl1 fixed at 0V.
If the Vctl1 and Vctl2 pins are connected together it ispossible to achieve the full analog attenuation rangewith only a small degradation in input IP3 performance.Applications include AGC circuits and temperaturecompensation of multiple gain stages in microwavepoint-to-point and VSAT radios.
Applications
- Point-to-Point Radio
- VSAT Radio
- Test Instrumentation
- Microwave Sensors
- Military, ECM & Radar
