Product Description The PE4271 is a is a high-isolation Switch designed for CATV applications, covering a broad frequency range from near DC up to 3000 MHz. 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 PE4271 provides for a cost effective and manufacturable solution vs. mechanical relays. The PE4271 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.
