P35-4211-1 Marconi Optical Components GaAs MMIC SPDT Reflective Switch, DC - 3GHz Features · · · · · Broadband performance Low insertion loss; 0.6dB typ at 1GHz Ultra low DC power consumption Fast switching speed; 3ns typical Low cost SO8 plastic package Description The P35-4211-1 is a high performance Gallium Arsenide monolithic single pole double throw RF switch, suitable for use in broadband communications and instrumentation applications. An open circuit reflective termination is presented at the isolated output 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. 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 surface-mount plastic SO8 package. It is also available as a bare die (see P35-4211-0). Electrical Performance Ambient temperature = 22± 3°C , ZO = 50Ω, Control voltages = 0V/-5V unless otherwise stated.
