Description
The P35-4245-0 is a high performance Gallium Arsenide double pole double throw broadband RF switch MMIC. 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 0.5碌m gate length MESFET process (S20) and is fully protected using Silicon Nitride
passivation for excellent performance and reliability. This device is also available packaged in plastic SO14 package (see
P35-4245-3).
