First SP4T switches for wideband and high frequency apps up to 67 GHz

pSemi unveiled what it claims as industry’s first SP4T switches for wideband and high frequency applications up to 67 GHz. The new SP4T switches designed to enhance 5G millimeter wave (mmWave) systems and short-range connectivity offer low insertion loss, higher linearity, shorter switching time and higher power handling at FR2 frequencies. pSemi says it now offers a family of mmWave SPDT and SP4T switches to help designers simplify layouts and improve overall system efficiency in test and measurement, wireless infrastructure, satellite and point-to-point communication applications.

These switches are suggested for implementation of phased array antennas and optimized RF front-end architectures to maximize signal strength and throughput without adding noise or loss to the system.

“Demand for enhanced streaming and augmented, virtual and mixed reality experiences are accelerating the commercialization of mmWave. pSemi continues to expand its portfolio of mmWave switches, digital step attenuators, beamformers and up-down converters, and to invest in technology that supports customer needs as higher frequency spectrum is released.” quotes Vikas Choudhary - Vice President, Sales & Marketing - Leadership

Features & Benefits:

Three UltraCMOS switches to meet challenging mmWave system designs from 9 kHz to 67 GHz. Available in flip-chip die form, the PE42545 SP4T supports up to 67 GHz, and the PE42525 SPDT supports up to 60 GHz. Available in a small 3 x 3 mm LGA package, the PE42546 SP4T supports up to 45 GHz.

New pSemi SP4T switches streamline and simplify filter bank designs.

pSemi suggests for test and measurement designers seeking to simplify complex broadband designs, a single PE42545 or PE42546 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.
