pSemi Corporation has recently introduced the PE44951, a revolutionary low-power, two-way phase shifter featuring digitally controlled step attenuation (DSA). The PE44951 operates in the 5.925 – 7.525 GHz range, and its introduction marks a significant leap forward in the field of wireless infrastructure technology.
New Products Showcased at MWC 2024
The corporation is set to exhibit its latest products, which include the newly announced PE562212 front end module (FEM) and the PE423211 SPDT switch, designed for automotive UWB solutions, at the Mobile World Congress (MWC) 2024. This premier event will be held between February 26 and February 29, 2024, in the cosmopolitan city of Barcelona, Spain. pSemi Corporation’s state-of-the-art technology will be featured at the Murata exhibit, located at Stand 5D66 in Hall 5.
PE44951: Revolutionizing Wireless Infrastructure
The PE44951 heralds a new era in the industry, coinciding with the release of the 6.425 – 7.125 GHz (n104) spectrum. This innovative product is the first highly integrated two-way phase shifter with DSA in the 5.925 to 7.525 GHz range, facilitating hybrid beamforming. The PE44951 is particularly effective in wireless infrastructure applications such as massive MIMO (mMIMO) macro and micro base stations, as well as future 5G solutions.
Unprecedented Integration of RF Solutions
The PE44951 combines a two-way phase shifter and DSA into a single, compact package, simplifying system integration and saving crucial board space. The design is streamlined for ease of development, and features an SPI interface for precise and flexible control. This reduces power consumption and further facilitates system integration.
Impressive Performance Range
Beyond its power consumption and efficiency, the PE44951 boasts a wide performance range, covering the entire 5.925 – 7.525 GHz band. The compact footprint of the PE44951, facilitated by pSemi’s UltraCMOS process, provides board space savings, making it a beneficial choice for space-constrained designs. The product also provides excellent isolation, low insertion loss, and high linearity, ensuring impeccable signal integrity for demanding network requirements.
Enabling Next-Generation Networks
Vikas Choudhary, Vice President of Global Sales, Marketing and Systems Engineering at pSemi, believes that the PE44951 is a major breakthrough for radio front end designers. It redefines front-end architectures for 5G radios by integrating two critical functions into a single chip, paving the way for simpler, more compact, and higher performing 5G base stations. This advancement is poised to accelerate the rollout of next-generation networks, delivering faster and more reliable wireless connectivity worldwide.
