Introduction

The PE4257 is a high-isolation UltraCMOS switch designed for wireless applications, covering a broad frequency range from near 10 MHz up to 3000 MHz. This single-supply SPDT switch integrates a two-pin 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 wireless application, the PE4257 provides unprecedented isolation and integration. The PE4257 is manufactured on pSemi’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.
