Product Details
The HMC941A die is a broadband 5-bit GaAs IC digital attenuator MMIC chip. Covering 0.1 to 30 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 less than ± 0.5 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.
APPLICATIONS
- Fiber optics and broadband telecom
- Microwave radio and VSAT
- Military radios, radar and ECM
