Description
The P35-4250-3 is a high performance Gallium Arsenide single pole four throw RF switch. It is suitable for use in
broadband communications and instrumentation applications. A short circuit reflective termination is presented at the
isolated outputs 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 0.5碌m 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 surface-mount plastic
package.
