Product Specification

PE42551

Product Description

The PE42551 RF Switch is designed to support the

requirements of the test equipment and ATE market. This

broadband general purpose switch maintains excellent RF

performance and linearity from 9 kHz through 6000 MHz. The

PE42551 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

PE42551 also exhibits outstanding isolation that approaches

21 dB at 6000 MHz and is offered in a small 4x4x0.85 mm

QFN package.

The PE42551 is manufactured on Peregrine’s UltraCMOS ?
