P35-4215-1R Marconi Optical Components GaAs MMIC SPDT Reflective Switch, DC - 4GHz Features · · · · · Broadband performance Low insertion loss; 0.5dB typ at 2GHz Ultra low DC power consumption Fast switching speed; 3ns typical Surface mount package Description The P35-4215-1R is a high performance Gallium Arsenide monolithic single pole double throw RF switch, suitable for use in broadband communications and instrumentation applications. A short circuit reflective termination is presented at the isolated output port of the switch. Control is effected by the application of complimentary 0V and -5V levels to the control lines in accordance with the truth table below. The 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. It is packaged in a hermetically sealed 8-lead gullwing flatpack for high performance and ease of mounting.
