PE4256
Product Description
The PE4256 is an UltraCMOS Switch designed for CATV applications, covering a broad frequency range from DC up to 3000 MHz. This single-supply SPDT switch integrates a twopin CMOS control interface. It also provides low insertion loss with extremely low bias requirements while operating on a single 3-volt supply. In a typical CATV application, the PE4256 provides for a cost effective and manufacturable solution when compared to mechanical relays. The PE4256 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.
