Description
The P35-4304-000-200 is a high performance Gallium Arsenide monolithic 6 bit digital attenuator offering an attenuation
range of 31.5dB in 0.5dB steps. 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 table below. The full attenuation range is achieved by modifying the control lines in
combination.
The die is fabricated using MOC's 0.5碌m gate length MESFET process (S20). It is fully protected using Silicon Nitride
passivation for excellent performance and reliability.
