13.5GHz SPDT switch

The PE42556 SPDT (single pole double throw) RF switch employs UltraCMOS silicon-onsapphire process technology, features broadband RF performance from 9kHz up to 13.5GHz without gate or phase lag and insertion loss drift and ensures fast switch-settling time. The switch has improved linearity, making it suitable for use in test and measurement applications including ATE (automated test equipment) and general purpose test & measurement; RF/IF transceiver signal switching; filter bank switching; and discrete DSA stages. The new absorptive switch terminates the unused port to 50Ω and delivers an isolation of 26 dB at 13.5 GHz and IIP3 of +56 dBm. ESD tolerance is 4.0kV HBM on all ports. Additional features include integrated CMOS control logic, driven by a single-pin, lowvoltage CMOS control input with a user-defined logic table, as well as a logicselect pin that allows inverted polarity for back-to-back switching applications. The PE42556 occupies a flip chip package with a 400-µm bump pitch.
