PE4312 - RF Digital Step Attenuator

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.

Product 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. 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 supports both serial and parallel programming of the attenuation, including the capability to program an initial attenuation state at power-up. Covering a 31.5 dB attenuation range in 0.5 dB steps, it maintains high linearity and low power consumption from 1 MHz through 4 GHz. PE4312 also features an external negative supply option, and is offered in a 20-lead 4 × 4 mm QFN package.
