346MS8G

      The 346MS8G is GaAs MMIC SMT VOLTAGE-VARIABLE ATTENUATOR designed for Point-to-Point Radio;VSAT Radio.The 346MS8GE has the following features including Wide Bandwidth: DC - 8 GHz;Low Phase Shift vs. Attenuation;32 dB Attenuation Range.
      The HMC346MS8G are absorptive Voltage Variable Attenuators (VVA) in 8 lead surface-mount packages operating from DC - 8 GHz. It features an on-chip reference attenuator for use with an external op-amp to provide simple single voltage attenuation control, 0 to -3V. The device is ideal in designs where an analog DC control signal must control RF signal levels over a 30 dB amplitude range. Applications include AGC circuits and temperature compensation of multiple gain stages in microwave point-to-point and VSAT radios.ALL GROUND LEADS AND GROUND PADDLE MUST BE SOLDERED TO PCB RF GROUND.
      The circuit board used in the fi nal application should be generated with proper RF circuit design techniques. Signal lines at the RF ports should be 50 ohm impedance and the package ground leads and package bottom should be connected directly to the PCB RF ground plane, similar to that shown above. The evaluation circuit board shown above is available from Hittite Microwave Corporation upon request. Information contained herein is intended to provide a product description only.
