Description
The P35-4227-5T 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. There is a choice of two line or four line control. Four line
control allows the use of an 'all-off' state.
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 SO14 surface mount plastic
package.
