From headquarters in San Diego and offices around the world, pSemi’s team explores new ways to make electronics for the connected world smaller, thinner, faster and better.



The PE4270 is a high-isolation switch designed for CATV applications, covering a broad frequency range from 1 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 3V supply. In a typical CATV application, the PE4270 provides for a cost-effective and manufacturable solution vs. mechanical relays.
