Product Specification
PE4280
Product Description
The PE4280 is an UltraCMOS? Switch designed for CATV
applications, covering a broad frequency range from DC up to
2.2 GHz. This single-supply SPDT switch integrates a two-pin
CMOS control interface. It also provides low insertion loss with
extremely low bias requirements while operating on a single 3 V
supply. In a typical CATV application, the PE4280 provides for a
cost effective and manufacturable solution when compared to
mechanical relays.
The PE4280 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.
