CMD172 Qorvo

CMD172 18-40 GHz Voltage Variable Attenuator Product Overview Key Features The CMD172 is wideband GaAs MMIC absorptive Voltage- Ultra Wideband Performance Variable Attenuator (VVA) die which operates from 18 to 40 Low Insertion Loss GHz. The VVA uses a single DC control voltage of -3V to Wide Attenuation Range 0V to control RF signal levels over a 37 dB dynamic range. Small Die Size The CMD172 has an extremely low insertion loss of 1.6 dB and is a 50 ohm matched design which eliminates the need for RF port matching. The CMD172 offers full passivation Ordering Information for increased reliability and moisture protection.
