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 in Peregrine’s patented Ultra Thin
Silicon (UTSi®) CMOS process, offering the performance of
GaAs with the economy and integration of conventional CMOS.
