P35-4232-P01-200 Marconi Optical Components GaAs MMIC SPDT Reflective Switch, DC - 2GHz Features · · · · · · Broadband performance Low insertion loss; 0.8dB typ at 1GHz Ultra low DC power consumption Fast switching speed; 3ns typical Positive or negative voltage operation SO8 plastic package Description The P35-4232-P01-200 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 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 0.5µm 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 plastic package.
