The PE4246 RF Switch is designed to cover a broad range of
applications from 1 to 5000 MHz. It is non-reflective at both
RF1 and RF2 ports. This SPST switch integrates a single-pin
CMOS control interface, and provides low insertion loss while
operating with extremely low bias from a single +3-volt supply.
In a typical application, the high isolation PE4246 can replace
multiple RF switches of lesser isolation performance. It is
offered in a small 3x3 mm DFN package.
The PE4246 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.
