Key Features
- Ultra wideband performance
- Low insertion loss
- Wide attenuation range
- Small die size
Qorvo's CMD324 is negative controlled, wideband GaAs MMIC 2-bit digital attenuator die which operates from DC to 30 GHz. Each bit of the attenuator is controlled by a single voltage of either 0 V or -5 V. The attenuator bit values are 10 dB and 20 dB, for a total attenuation of 30 dB. The CMD324 has a low insertion loss of 2.9 dB at 15 GHz and the attenuation accuracy is typically less than 10 % step error. The CMD324 is a 50 ohm matched design which eliminates the need for RF port matching. The CMD324 offers full passivation for increased reliability and moisture protection.
Typical Applications
- Electronic Warfare (EW)
- Radar
