Description
The P35-4310-000-200 is a high performance Gallium Arsenide monolithic single bit absorptive
step attenuator. It is suitable for use in broadband communications, instrumentation and electronic
warfare applications. The attenuator is controlled by the application of complimentary 0V/-5V
or 0/-8V signals to the control lines in accordance with the truth tables below.
The die is fabricated using MCL's 0.5碌m gate length MESFET process (S20). It is fully protected
using Silicon Nitride passivation for excellent performance and reliability.
