pSemi pushes the limits of 5G mmWave switching up to 67 GHz


The emergence of millimeter waves
With growing investments in Augmented Reality (AR), Virtual Reality (VR), and Artificial Intelligence (AI) devices and applications, mmWave frequencies are critical to delivering faster data rates, increased throughput, and lower latency in advanced communication networks. 5G mmWave and multiband configurations introduce more complex signal transmission and denser antenna structures to support evolving cellular, satellite, and license-free standards. Designers overcome these challenges by implementing phased array antennas and RF front-end architectures optimized to maximize signal power and throughput without adding noise or loss to the system.

“Demand for enhanced streaming and augmented, virtual and mixed reality experiences is accelerating mmWave’s commercialization,” says Vikas Choudhary, vice president of sales and marketing at pSemi. “pSemi continues to expand its portfolio of mmWave switches, digital pitch attenuators, beamformers and high-to-low converters, and to invest in technology that meets customer needs as the frequency spectrum higher is released. »

Broadband RF Switch Features and Benefits
Three UltraCMOS® switches deliver RF performance, reliability, and size in multiple product configurations to best meet challenging mmWave system designs from 9 kHz to 67 GHz. Available in flip-chip matrix 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.

  • Low latency — Extremely fast switching for fast transmit and receive data patterns in advanced communication schemes.
  • Energetic efficiency — Highest power handling and lowest insertion loss to conserve transmit power and increase receiver sensitivity.
  • Broadband coverage — Best-in-class return loss with proprietary design techniques delivers RF performance up to 67 GHz.

Test and measurement – a mmWave SP4T case study
The test and measurement industry faces the unique challenge of having to stay ahead of the 5G mmWave technology learning curve to deliver advanced test solutions. The equipment must support higher power handling, high linearity, low insertion loss, and fast switching to effective pressure test scenarios up to 67 GHz under extreme conditions.

For test and measurement designers looking to simplify complex wideband designs, a single PE42545 or PE42546 SP4T can replace multiple SPDTs used in cascaded filter bank configurations to reduce space and provide tape with less insertion loss. Access to scalable and reliable components allows designers to easily adapt system designs to different band configurations as 3GPP standards evolve into 5G, 5G-Advanced and 6G.
