Key Features
- Low insertion loss
- Positive gain slope
- Small die size
- Ultra wideband performance
- Wide attenuation range
Qorvo's CMD172 is a wideband, RF / Microwave GaAs MMIC absorptive Voltage-Variable Attenuator (VVA) die which operates from 18 to 40 GHz. The VVA uses a single DC control voltage of -3V to 0V to control RF signal levels over a 37 dB dynamic range. The CMD172 attenuator MMIC 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 also offers full passivation for increased reliability and moisture protection.
