PE4240
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 Ultra CMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of Ga As with the economy and integration of conventional CMOS.
