Product Specification
PE4283
Product Description
The PE4283 RF Switch is designed to cover a broad range
of applications from DC through 4000 MHz. This reflective
switch integrates on-board CMOS control logic with a low
voltage CMOS-compatible control interface, and can be
controlled using either single-pin or complementary control
inputs. The PE4283 operates using a +3 volt power supply.
The PE4283 SPDT High Power RF Switch 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.
