Overview

1.0 dB LSB Steps to 31 dB
Single Positive Control Line Per Bit
Insertion loss: 6.4 dB typical at 40 GHz
Excellent Attenuation accuracy

±1.0 dB Typical Bit Error
High Input IP3: +43 dBm
Power handling: +25 dBm
Dual-supply operation: ±5 V

The ADH939S is a broadband 5-bit GaAs IC digital attenuator supplied in die form with Class K element evaluation. Covering 0.1 to 40.0 GHz, the insertion loss is less than 6.4 dB typical @ 40.0 GHz. 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.

The ADH939S requires dual supply voltages, Vdd = +5 V and Vss = -5V, and five control voltage inputs, toggled between +5V and 0V to select each attenuation state.
