Description
The P35-4232-000-200 is a high power Gallium Arsenide single pole double throw broadband RF switch MMIC. It is
suitable for use in broadband communications and instrumentation applications. A high impedance reflective termination
is presented at the isolated output of the switch. Control is effected by the application of complimentary 0V/-5V or 0/-8V
signals to the control lines in accordance with the truth table. Alternatively, positive control voltages may be used if the
Vref terminal is connected to the positive supply and decoupled to a good RF ground. In this case DC blocking capacitors
should be used in series with the input and output RF connections.
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 a low-cost plastic package
or higher performance ceramic package.
