Product Specification
PE4259
Product Description
The PE4259 UltraCMOS? RF switch is designed to
cover a broad range of applications from 10 MHz
through 3000 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. Using a nominal +3-volt power supply
voltage, a typical input 1 dB compression point of
+33.5 dBm can be achieved.
The PE4259 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.
