Features

1.0 dB LSB steps to 31 dB
Single positive control line per bit
±1.0 dB typical bit error
High input IP3: +43 dBm
Die size: 2.34 x 1.0 x 0.1 mm

Additional Details

The HMC939A 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.

Applications

Fiber optics and broadband telecom
Microwave radio and VSAT
Military radios, radar and ECM
Space applications
