SPDT RF Switch Delivers High Linearity, Fast Settling Time for ATE, Transceiver Applications
Portable Design News, Thursday July 24, 2008
Peregrine Semiconductor Corporation has announced the new PE42552 SPDT 50-Ohm RF Switch, designed for use in Test and Measurement (T&M) applications requiring ultra-linear RF performance and ultra-fast settling time, such as Automated Test Equipment (ATE), RF/IF transceiver signal switching, filter bank switching and discrete digital step attenuator (DSA) stages.
Integrated CMOS control logic, driven by a single-pin, low-voltage CMOS control input, features a novel user-defined logic table. Further, the device includes a logic-select pin which inverts logic polarity for back-to-back switching applications, changing the logic definition of the control pin. The PE42552, designed on Peregrine’s HaRP-enhanced UltraCMOS silicon-on-sapphire process technology, maintains excellent broadband RF performance from 9 kHz up to 7.5 GHz without gate lag and phase drift, and ensures fast switch-settling time. This innovative feature of the UltraCMOS process provides best-in-class linearity and superior performance to GaAs with the economy an integration of conventional CMOS.
“The PE42552 delivers the industry’s fastest settling time and the highest linearity performance available in a RF broadband solid state switch,” stated Mark Schrepferman, product marketing director for commercial and industrial products. “These attributes make the PE42552 a tremendous tool for extreme performance environments such as the test equipment market,” he added.
The PE42552 exhibits outstanding isolation of 47 dB (3.0 GHz) and approaching 30 dB at 7.5 GHz; high ESD tolerance of 1.0 kV HBM on all ports; and IIP3 of +65 dBm. The device, offered in the RoHS¬-compliant 16-lead 3x3x0.75mm QFN package, is available for sampling in July 2008 and is priced in volume at $3.34 (100Ku).
