P35-4245-3 GaAs MMIC DPDT REFLECTIVE SWITCH, DC - 2GHz Features • Broadband performance • Low insertion loss; 0.7dB typ at 1GHz • • Ultra low DC power consumption Fast switching speed; 3ns typical • SO14 surface mount package Description The P35-4245-3 is a high performance Gallium Arsenide double pole double throw RF switch. 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. This die is fabricated using MCL'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 lowcost SOIC14 surface-mount plastic package.
