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
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.
