主要特点
- 宽带性能
- Low insertion loss
- 宽衰减范围
- 无铅RoHs兼容3x3 QFN封装
Qorvo's CMD280C3 is a negative controlled, wideband GaAs MMIC 5-bit digital attenuator housed in a leadless 3x3 mm surface mount package. Each bit of the attenuator is controlled by a single voltage of either 0 V or -5 V. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB, for a total attenuation of 15.5 dB. The CMD280C3 has a low insertion loss of 3 at 10 GHz and the attenuation accuracy is typically 0.1 dB step error. The CMD280C3 is a 50 ohm matched design which eliminates the need for RF port matching.

X-微波设计系统
本产品可作为X-微波块（X-MWblock）进行评估。
X-MWB模块s are RF and microwave "drop-in" components that can be used individually for prototyping or in production assemblies. X-MWblocks are easy to test, integrate, align, and configure to 60 GHz and beyond. No messy sweat soldering or silver epoxy processes are required. X-MWblocks are highly characterized with S-parameter models and connect with a patented solder-less interconnect technology.
