Features and Benefits
- 0.5 dB LSB steps to 15.5 dB
- Single positive control line per bit
- ±0.5 dB typical bit error
- High input IP3: +45 dBm
- 16mm2 leadless SMT plastic package
The HMC941ALP4E is a broadband 5-bit GaAs IC digital attenuators in low cost leadless surface mount packages. Covering 0.1 to 33.0 GHz, the insertion loss is less than 4 dB typical. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, for a total attenuation of 15.5 dB. Attenuation accuracy is excellent at ±0.3 dB typical step error with an IIP3 of +45 dBm. Five control voltage inputs, toggled between +5V and 0V, are used to select each attenuation state.
