Product Specification
PE4240
Product Description
The PE4240 is a high-isolation MOSFET Switch designed for
CATV applications, covering a broad frequency range from
DC up to 1.3 GHz. This single-supply SPST switch offers a
single-pin CMOS control interface with industry leading CTB
performance. It also provides low insertion loss, high isolation
and extremely low bias requirements while operating on a
single 3-volt supply. In a typical CATV application, the
PE4240 provides for a cost effective and manufacturable
solution vs. mechanical relays.
The PE4240 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.
