The AT002D4-31 is an MMIC FET digital attenuator

consisting of four monolithic attenuators with an LSB of

2 dB and a total attenuation of 30 dB with all attenuators

connected. This attenuator is recommended for fast

response, low power consumption AGC circuits. Typical

applications include AGC circuits for radar processing,

instrumentation and levelers in RF equipment.
