pSemi® Corporation announced its newest SP4T switches up to 8 GHz, PE42445 and PE42446, and two multi-chip modules featuring dual-channel switches, the PE53230 for 3.3 to 3.8 GHz and the PE53231 for 3.5 to 4.0 GHz.

PE42445 and PE42446

The PE42445 high isolation 3×3 mm package and the PE42446 high isolation 4×4 mm package switches deliver high linearity and best-in-class isolation performance, essential in 5G base stations. The new PE42445 and PE42446 switches integrate seamlessly into 4G and 5G base stations and mMIMO architecture, providing digital pre-distortion (DPD) feedback loops and transmitter monitoring signal paths to prevent interference and maintain signal integrity, given massive MIMO applications. Thanks to their high reliability and extended operating temperature range, the new high isolation SP4T switches can be used for a wide variety of applications, including DPD and VSWR monitoring, portable wireless radios, repeaters and E911 systems and test and ATE equipment.

Offered in a 20-lead (3×3 mm) LGA package and 24-lead (4×4 mm) LGA package, the PE42445 and PE42446 switches offer greater than 60 dB isolation, preventing interference and maintaining signal integrity. They are built for extended operating temperatures ranging from -40°C to +125°C. Based on customer requirements for high isolation SP4T switches, the new products are designed for applications ranging from DPD feedback loops to transmitter monitoring signal paths, with low insertion loss across the band, high linearity of 60 dBm IIP3, and fast switching time of 250 nsec.

PE53230 and PE53231

Each module contains two switches and two LNAs for high and low band frequencies. The new module portfolio delivers the lowest noise figure in the industry, at less than 1 dB, enabling best-in-class receiver sensitivity and performance while handling 20 W 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.

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