PE4312 - Peregrine Semiconductor

PE4312 RF Digital Step Attenuator

The PE4312 is a 50Ω, HaRP™ technology-enhanced 6-bit RF Digital Step Attenuator (DSA) designed for use in 3G/4G wireless infrastructure and other high performance RF applications. This DSA is a pin-compatible upgraded version of the PE4302 with higher linearity, improved attenuation accuracy and faster switching speed. An integrated digital control interface.

Features

an external negative supply option, and is offered in a 20-lead 4 × 4 mm QFN package. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports. The PE4312 is manufactured on pSemi’s UltraCMOS® process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate. pSemi’s HaRP™ technology enhancements deliver high linearity and excellent harmonics performance. It is an innovative feature of the UltraCMOS® process, offering the performance of GaAs with the economy and integration of conventional CMOS. Product Specification PE4312 Ult.
