CMD282 RF Variable Attenuator by Custom MMIC

Courtesy of everything RF : RF Variable Attenuator by Custom MMIC

The CMD282 from Custom MMIC is a 2-bit Digital Attenuator that operates from DC to 40 GHz. Each bit of the attenuator is controlled by a single voltage of either 0 V or –5 V. The attenuator bit values are 4 dB and 8 dB, for a total attenuation of 12 dB. The CMD282 has a low insertion loss of 1.5 dB at 18 GHz and the attenuation accuracy is typically 0.1 dB step error. It is matched to 50 ohms and is available as a die that offers full passivation for increased reliability and moisture protection.
