HMC346AMS8GE

HMC346AMS8GE v03.1119 ATTENUATORS - SMT 8 GaAs MMIC SMT VOLTAGE-VARIABLE ATTENUATOR, DC - 8 GHz Typical Applications Features This attenuator is ideal for use as a VVA for DC - 8 GHz applications: Wide Bandwidth: DC - 8 GHz • Point-to-Point Radio 32 dB Attenuation Range Low Phase Shift vs. Attenuation • VSAT Radio General Description Functional Diagram The HMC346AMS8GE is 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 -5V. 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.
