HMC941 / HMC941LP4 0.5 dB LSB, 5 Bit, Digital Attenuator Chip or SMT, 0.1 GHz to 30 GHz or 33 GHz

The HMC941 devices are broadband, 5-bit, GaAs, IC digital attenuators available in a low cost, leadless, surface-mount package or in a monolithic microwave integrated circuit (MMIC) chip. Covering 0.1 GHz to 30 GHz or 33 GHz, the insertion loss is less than 4 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, and 8 dB for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.3 dB or less than ±0.5 dB typical step error with an IIP3 of +45 dBm. Five control voltage inputs, toggled between +5 V and 0 V, are used to select each attenuation state.
