Product Specification
PE4245
Product Description
The PE4245 RF Switch is designed to cover a broad range of
applications from near DC to 4000 MHz. This switch integrates
on-board CMOS control logic with a low voltage CMOS
compatible control input. Using a +3-volt nominal power
supply voltage, a 1 dB compression point of +27 dBm can be
achieved. The PE4245 also exhibits excellent isolation of
better than 42 dB at 1000 MHz and is offered in a small 3x3
mm DFN package.
The PE4245 is manufactured on Peregrine鈥檚 UltraCMOS鈩?/div>
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.
