pSemi Announces Industry-leading 5G mmWave Switch Reaches Volume Production

5G mmWave Switch

SP4T Switch Portfolio Enables Wideband and High Frequency Applications

SAN DIEGO – September 27, 2022 – pSemi® Corporation, a Murata company focused on semiconductor integration, announces the production readiness of a new SP4T switch targeted for wideband and high frequency applications up to 67 GHz.

An industry-first, this compact and energy-efficient switch is designed to enhance 5G millimeter wave (mmWave) systems and short-range connectivity. Offering best-in-class insertion loss, linearity, switching time and power handling for frequencies up to 67 GHz, the PE42545 is part of a family of mmWave switches that can help designers simplify layouts and improve overall system efficiency in test and measurement, wireless infrastructure, non-terrestrial networks and point-to-point communication applications.

“As commercial mmWave deployment accelerates, our customers need high-performance switches that are broadband, very low insertion loss and stellar return loss for a high-performing mmWave signal chain. With more than 30 years of expertise in high-frequency semiconductor invention and manufacturing, pSemi provides high-performance, dependable mmWave solutions that our customers and partners can count on.”

A mmWave SP4T Case Study

Test & Measurement

The test and measurement industry faces the unique challenge of needing to stay ahead of the 5G mmWave technology learning curve to deliver advanced testing solutions. Equipment must support higher power handling, high linearity, low insertion loss and fast switching to efficiently pressure test scenarios up to 67 GHz under extreme conditions.

New pSemi SP4T switch streamlines and simplifies filter bank designs.

For test and measurement designers seeking to simplify complex broadband designs, a single PE42545 SP4T can replace multiple SPDTs used in cascaded filter bank configurations to reduce space and offer band-select paths with less insertion loss. Having access to scalable and reliable components ensures designers can easily adapt system designs to different band configurations as 3GPP standards evolve in 5G, 5G-Advanced and 6G.
