HMC346MS8GE

HMC346MS8G / 346MS8GE v07.1008 GaAs MMIC SMT VOLTAGE-VARIABLE ATTENUATOR, DC - 8 GHz 5 Typical Applications This attenuator is ideal for use as a VVA for DC - 8 GHz applications: Point-to-Point Radio VSAT Radio Features Wide Bandwidth: DC - 8 GHz Low Phase Shift vs. Attenuation 32 dB Attenuation Range ATTENUATORS - SMT Functional Diagram General Description The HMC346MS8G & HMC346MS8GE 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.
