Product Description The PE4248 is a high-isolation MOSFET Switch designed for CATV applications, covering a broad frequency range from DC up to 1.3 GHz. This singlesupply 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 PE4248 provides for a cost effective and manufacturable solution vs. mechanical relays. The PE4248 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. Figure 1.
