Description
The P35-4227-3R is a high performance Gallium Arsenide single pole double throw broadband RF switch. It is suitable
for use in broadband communications and instrumentation applications. A short circuit reflective termination is presented
at the isolated output of the switch. The switch is controlled by the application of complimentary 0V/-5V or 0/-8V signals to
the control lines in accordance with the truth table below.
This die is fabricated using MOC's 0.5µm gate length MESFET process (S20) and is fully protected using Silicon Nitride
passivation for excellent performance and reliability. This device is packaged in a low-cost SO8 surface mount plastic
package.
