HMC939 / HMC939LP4
1 dB LSB, 5-Bit, Digital Attenuator Chip or SMT, 0.1 GHz to 33 GHz or 40 GHz
The HMC939 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 33.0 GHz or 40 GHz, the insertion loss is less than 5 dB typical. The attenuator bit values are 1.0 (LSB), 2, 4, 8, and 16 dB for a total attenuation of 31 dB. Attenuation accuracy is excellent at less than ±0.4 or ±1.0 typical step error with an IIP3 of +43 dBm. Five control voltage inputs, toggled between +5 V and 0 V, are used to select each attenuation state.
