PRODUCTION
The ADH346S devices are absorptive, voltage variable attenuators (VVAs) operating from DC to 20 GHz supplied in die form with Class K element evaluation. 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.
