Product Specification
PE42552
Product Description
The PE42552 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 DC through 7500 MHz. The PE42552 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 novel user defined logic table, enabled by the
on-board CMOS circuitry. The PE42552 also exhibits
outstanding isolation of 44 dB at 7500 MHz, fast settling time,
and is offered in a tiny 3x3 mm QFN package.
The PE42552 is manufactured on Peregrine’s UltraCMOS™
process, a patented variation of silicon-on-insulator (SOI)
technology on a sapphire substrate, offering the performance of
GaAs with the economy and integration of conventional CMOS.
