Description
The P35-4227-3T 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 50鈩?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 0.5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 SO8 surface mount plastic
package.
