Description
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.
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 performa.
