Overview

  • Wide bandwidth: dc to 8 GHz, 14 GHz, 18 GHz, or 20 GHz
  • Low phase shift vs. attenuation
  • 30 dB or 32 dB attenuation range
  • Simplified voltage control

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.
