Digital Attenuators
Hittite announces the release of two GaAs MMIC digital attenuators which are suitable for wireless infrastructure, test equipment, microwave radio, and military applications from 0.7 to 3.8 GHz. The HMC271LP4 is a 5-bit digital attenuator with a 1 dB LSB and operates from 0.7 to 3.8 GHz with a typical insertion loss of 2.1 dB. The HMC271LP4 can be programmed to provide any attenuation state from 1 to 31 dB, in 1 dB steps with a ± 0.5 dB accuracy. The HMC305LP4 is a 5-bit digital attenuator with a 0.5 dB LSB and covers 0.7 to 3.8 GHz with a typical insertion loss of 1.5 dB. The HMC305LP4 can be programmed to provide any attenuation state from 0.5 dB to 15.5 dB, in 0.5 dB steps with a ± 0.3 dB accuracy. These digital attenuators offer input IP3 of up to +52 dBm without the need for an internally generated or externally supplied negative voltage. Each attenuator is matched to 50Ω at all attenuation levels.
