HMC985A - GaAs MMIC VOLTAGE - VARIABLE ATTENUATOR

General Description

The HMC985A is an absorptive Voltage Variable Attenuator (VVA) which operates from 20 - 50 GHz and is ideal in designs where an analog DC control signal must be used to control RF signal levels over a 37 dB dynamic range.

Key Features

  • Wide Bandwidth: 20 - 50 GHz Excellent Linearity: +32 dB Input IP3 Wide Attenuation Range: 37 dB Die Size: 2.78 x 1.41 x 0.1 mm General.
