pSemi Launches 3.5 GHz Dual-Channel Switch + LNA Module with Industry’s Lowest Noise Figure

Posted Date: 2023-06-20

SAN DIEGO – June 13, 2023 – pSemi® Company, a Murata firm main within the design and growth of semiconductor integration, right now introduced two multi-chip modules that includes dual-channel switches,  the PE53230 for 3.3–3.8 GHz and the PE53231 for 3.5–4.0 GHz. Every module accommodates two switches and two LNAs for prime and low band frequencies. The brand new module portfolio delivers the bottom noise determine within the trade, at lower than 1 dB, enabling best-in-class receiver sensitivity and efficiency whereas dealing with 20W common enter energy enabling removing of exterior circuitry.

Constructed for purposes throughout wi-fi infrastructure together with TDD-LTE macro and micro cells, 5G large MIMO techniques and TDD-based communication techniques, the brand new modules function excessive achieve and achieve flatness. They will operate as a failsafe with surprising high-power indicators coming in from Tx, whereas bettering receiver channel sensitivity with low noise figures. Combining excessive linearity (IIP3) with low energy consumption, the brand new modules are extremely built-in options that don't require any exterior matching networks.

 “We're proud to set the file with the bottom noise determine the trade has ever seen, delivering higher receiver sensitivity and better efficiency for our prospects’ techniques,” mentioned Vikas Choudhary, vp of worldwide gross sales, advertising and system engineering, pSemi. “By offering MIMO structure with the very best degree of integration of receiver entrance finish, we obtain excessive energy dealing with, excessive linearity, and low noise-figure for 5G mMIMO lively antenna techniques – serving to advance your entire wi-fi ecosystem.”

Supplied in a compact 6×6mm LGA package deal, the PE53230 and PE53231 merchandise function excessive achieve of greater than 36 dB and fast-switching time of lower than 600 nanoseconds. With low energy consumption of lower than 500mW/channel, these built-in options lead the trade with the very best common enter energy dealing with at 20W.

Samples for the PE53230 and PE53231 can be found now and are anticipated to be commercially obtainable Q1 2024. For extra data, please go to and, respectively.
