pSemi® Corporation announced the PE44951, a low-power, two-way phase shifter with digitally controlled step attenuation (DSA) for applications within the 5.925 to 7.525 GHz range. pSemi will showcase its latest innovative products ideal for IoT connectivity, including the recently announced PE562212 front-end module and the PE423211 SPDT switch, an automotive UWB solution, at Mobile World Congress (MWC) 2024, taking place February 26 –29, 2024, in Barcelona, Spain. pSemi's cutting-edge technology will be showcased at the Murata exhibit, located at Stand 5D66 in Hall 5.

PE44951: Redefining Wireless Infrastructure

The PE44951 marks a significant advancement in the industry, as the 6.425 to 7.125 GHz (n104) spectrum becomes available. The solution is the first highly integrated two-way phase shifter with DSA in the 5.925 to 7.525 GHz range to enable hybrid beamforming. This innovative product shines in wireless infrastructure applications like massive MIMO (mMIMO) macro and micro base stations, as well as next-generation 5G solutions.

This breakthrough in integrated RF solutions combines a two-way phase shifter and DSA in a single compact package. Minimizing board space and simplifying system integration, this innovative design streamlines the development process. Moreover, its SPI interface achieves precise and flexible control, reducing power consumption and ensuring seamless system integration.

"The PE44951 represents a major breakthrough for radio front-end designers tasked with redefining front-end architectures for 5G radios," said Vikas Choudhary, vice president of global sales, marketing and systems engineering at pSemi. "By integrating two critical functions into a single chip, we're enabling simpler, more compact and higher performing 5G base stations. This will accelerate the deployment of next-generation networks and deliver faster, more reliable wireless connectivity globally."

The PE44951's advantages expand beyond power consumption and efficiency as it boasts an impressive performance range, covering the entire 5.925 to 7.525 GHz band. The PE44951's compact footprint, enabled by pSemi's UltraCMOS® process, provides valuable board space savings, making it ideal for space-constrained designs. Excellent isolation, low insertion loss and high linearity deliver uncompromising performance, guaranteeing exceptional signal integrity for networks with demanding needs.

With its combination of integrated functionality, compact size, digital precision, broad spectrum coverage and unmatched performance, the PE44951 empowers infrastructure companies to achieve new levels of design flexibility and performance.
