Description
AI
The HMC346 devices are absorptive, voltage variable attenuators (VVAs) operating from dc to 8 GHz, 14 GHz, 18 GHz, or 20 GHz. They feature on-chip reference attenuators for use with an external op-amp to provide simple single voltage attenuation control, 0 V to −3 V. These devices are ideal in designs when 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 radios and test instrumentation.ApplicationsPoint-to-point radiosVSAT radioBase station infrastructureFiber optics and broadband telecomMicrowave radio and VSATMilitary radios, radar, and ECMTest instrumentation
