The PE42556 RF Switch is designed for use in Test/ATE, cellular and other wireless applications. This broadband general purpose switch maintains excellent RF performance and linearity from 9kHz through 13500 MHz. The PE42556 integrates on-board CMOS control logic driven by a single-pin, low voltage CMOS control input. It also has a logic select pin which enables changing the logic definition of the control pin. Additional features include a user defined logic table, enabled by the on-board CMOS circuitry. The PE42556 also exhibits excellent isolation of 26 dB at 13500 MHz, fast settling time, and is offered in a tiny flip-chip package. Peregrine's HaRP™ technology enhancements deliver high linearity and excellent harmonics performance with the economy and integration of conventional CMOS.
