Product Specification
PE4239
SPDT UltraCMOS? RF Switch
Product Description
The PE4239 UltraCMOS? RF Switch is designed to cover a
broad range of applications from DC through 3.0 GHz. 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 +27 dBm can be achieved.
The PE4239 UltraCMOS? 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.
