HMC939 1 dB LSB 5-Bit Digital Attenuator Chip, 0.1 - 40 GHz
The HMC939 die is a broadband 5-bit GaAs IC digital attenuator MMIC chip. Covering 0.1 to 40 GHz, the insertion loss is less than 5 dB typical. The attenuator bit values are 1.0 (LSB), 2, 4, 8, 16 for a total attenuation of 31 dB. Attenuation accuracy is excellent at less than ±1.0 dB typical step error with an IIP3 of +43 dBm. Five control voltage inputs, toggled between +5V and 0V, are used to select each attenuation state.
