P35-4227-5T Marconi Optical Components GaAs MMIC SPDT Terminated Switch, DC - 3GHz Features · · · · · · Broadband performance High Isolation; 50dB typ at 1GHz Ultra low DC power consumption Fast switching speed; 3ns typical SO14 surface mount plastic package 4 line control permits 'all-off' state Description The P35-4227-5T 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. 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. This device is packaged in a low-cost SO14 surface mount plastic package.
