    pSemi Corporation is a Murata company driving semiconductor integration. pSemi builds on Peregrine Semiconductor’s 30-year legacy of technology advancements and strong IP portfolio but with a new mission—to enhance Murata’s world-class capabilities with high-performance semiconductors. With a strong foundation in RF integration, pSemi’s product portfolio now spans power management, connected sensors, optical transceivers, antenna tuning and RF frontends. These intelligent and efficient semiconductors enable advanced modules for smartphones, base stations, personal computers, electric vehicles, data centers, IoT devices and healthcare.



    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.
