pSemi ra mắt bộ chuyển kênh đôi 3,5 GHz + mô-đun LNA <con số nhiễu 1dB

15 June 2023

Murata company pSemi Corp of San Diego, CA, USA – a fabless provider of radio-frequency integrated circuits (RFICs) based on silicon-on-insulator (SOI) – has announced two multi-chip modules featuring dual-channel switches. The PE53230 for 3.3–3.8GHz and the PE53231 for 3.5–4.0GHz each contain two switches and two LNAs for high- and low-band frequencies. The new module portfolio is said to deliver the industry’s lowest noise figure, at less than 1dB, enabling best-in-class receiver sensitivity and performance while handling 20W average input power, enabling removal of external circuitry.

Built for applications across wireless infrastructure including TDD-LTE macro and micro cells, 5G massive MIMO systems and TDD-based communication systems, the new modules feature high gain and gain flatness. They can function as a failsafe with unexpected high-power signals coming in from Tx, while improving receiver channel sensitivity with low noise figures. Combining high linearity (IIP3) with low power consumption, the new modules are highly integrated solutions that do not require any external matching networks.

“We are proud to set the record with the lowest noise figure the industry has ever seen, delivering better receiver sensitivity and higher performance for our customers’ systems,” says Vikas Choudhary, VP of global sales, marketing & system engineering. “By providing MIMO architecture with the highest level of integration of receiver front end, we achieve high power handling, high linearity, and low noise figure for 5G mMIMO active antenna systems – helping advance the entire wireless ecosystem.”

Offered in a compact 6mm x 6mm LGA package, the PE53230 and PE53231 products feature high gain of more than 36dB and fast switching time of less than 600ns. With low power consumption of less than 500mW/channel, the integrated solutions are claimed to lead the industry with the highest average input power handling at 20W.

Samples for the PE53230 and PE53231 are available now and are expected to be commercially available first-quarter 2024.
