P35-4227-3T Marconi Optical Components GaAs MMIC SPDT Terminated Switch, DC - 3GHz Features · · · · · Broadband performance High Isolation; 45dB typ at 1GHz Ultra low DC power consumption Fast switching speed; 3ns typical SO8 surface mount plastic package Description The P35-4227-3T 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 50Ω 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 0.5µm 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 SO8 surface mount plastic package.

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 0.5µm gate length MESFET process (S20) and is fully protected using Silicon Nitride passivation for excellent performance and reliability.
