Data sheet GaAs MMIC SP4T Reflective Switch, DC - 2GHz The P35-4250-3 is a high performance Gallium Arsenide single pole four throw broadband RF switch. It is suitable for use in broadband communications and instrumentation applications. A short circuit reflective termination is presented at the isolated outputs 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. Features * Broadband performance * Low insertion loss; 0.7dB typ at 1GHz * Ultra low DC power consumption * Fast switching speed; 3nS typical * SO16 surface mount package This die is fabricated using Bookham's 0.5mm 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 surfacemount plastic package. www.bookham.com Thinking RF solutions P35-4250-3 Electrical Performance Ambient temperature = 223C, Zo = 50, Control voltages = 0V/-5V unless otherwise stated Parameter Insertion Loss 1 Isolation1 Input Return Loss2 Output Return Loss2 1dB power compression point3 Switching Speed Conditions Min Typ Max DC - 1GHz 1 - 2GHz DC - 1GHz 1 - 2GHz DC - 1GHz 1 - 2GHz DC - 1GHz 1 - 2GHz 0/-5V Control; 50MHz 0/-5V Control; 2GHz 0/-8V Control; 50MHz 0/-8V Control; 2GHz 50% Control to 10%90%RF 26 16 21 14 21 14 - 0.7 0.9 28 20 28 25 28 22 19 22.5 21.5 30 3 0.9 1.1 - Units dB dB dB dB dB dB dB dB dBm dBm dBm dBm ns Notes 1.
