Description
The P35-4211-1 is a high performance Gallium Arsenide monolithic single pole double throw RF switch, suitable for use in
broadband communications and instrumentation applications. An open circuit reflective termination is presented at the
isolated output of the switch. Control is effected by the application of complimentary 0V and -5V levels 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 SO8
package. It is also available as a bare die (see P35-4211-0).
