Product Introduction
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. In addition, no external blocking capacitors are required if 0 VDC is present on the RF ports.
The PE4312 is manufactured on Peregrine’s UltraCMOS process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate.
Peregrine’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.
