pSemi PE42445 & PE42446 High-Isolation SP4T Switches
pSemi PE42445 and PE42446 High-Isolation SP4T Switches feature broadband frequency coverage of up to 8GHz. PE42445 3mm x 3mm package and PE42446 4mm x 4mm package switches deliver high linearity and best-in-class isolation performance, essential in 5G base stations. pSemi PE42445 and PE42446 High-Isolation SP4T Switches integrate seamlessly into 4G and 5G base stations and mMIMO architecture. This integration provides digital pre-distortion (DPD) feedback loops and transmitter monitoring signal paths to prevent interference and maintain signal integrity in massive MIMO applications. High reliability and an extended operating temperature range allow these SP4T switches to be used for a wide variety of applications, including DPD and VSWR monitoring, portable wireless radios, repeaters/E911 systems, and test/ATE equipment.Features
