- Low insertion loss
- Wide attenuation range
- Pb-free Ro Hs pliant 3x3 QFN package
Description
The CMD280C3 is a negative controlled, wideband Ga As 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 d B, for a total attenuation of 15.5 d B. The CMD280C3 has a low insertion loss of 3 at 10 GHz and the attenuation accuracy is typically 0.1 d B step error. The CMD280C3 is a 50 ohm matched design which eliminates the need for RF port matching.
