A Murata company, pSemi® Corporation has announced the production readiness of two new mmWave ICs targeted for active antenna systems in 5G base stations, customer premises equipment and point-to-point radio communication applications. In addition to the 8-channel beamforming front end and dual-channel up-down converter ICs, pSemi offers a complete support package of tools and technical expertise to simplify mmWave design and development. The new RF SOI ICs are the latest in our mmWave portfolio that offers full IF-to-RF coverage across the n257, n258, and n260 bands in the industry’s smallest form factors.

“As the n257 band reaches global mainstream use, pSemi is pleased to introduce a suite of mmWave products and tools to support this growing demand,” says Vikas Choudhary, vice president of sales and marketing at pSemi. “With an established history in high-frequency semiconductor innovation and manufacturing, pSemi has the expertise and infrastructure required to deliver mmWave products with the performance and quality our customers and partners can trust.”

The PE188200 beamformer IC (n257 band) and PE128300 up-down converter IC (n257, n258 band) offer a wide range of features and benefits to 5G FR2 system designers, including the smallest footprint per channel and full IF-to-RF coverage. Monolithically integrated RF SOI ICs with the industry’s smallest form factors make it easy to build large arrays without the need for extra routing. The mmWave up-down converters can be paired with up to four pSemi beamformers to support massive-MIMO, hybrid-beamforming and other active antenna configurations.

Additionally, the PE188200 8-channel beamformer IC enables flexible antenna design by supporting four dual-polarized or eight single-polarity antenna elements, and scaled configurations for optimum array gain, EIRP, and antenna directivity. Additionally, linear POUT at the desired EVM with low RMS phase and amplitude error for increased array gain and antenna directivity ensures accurate beamforming.

The highly integrated PE128300 dual-channel up-down converter IC saves expensive real estate with the smallest footprint with best-in-class performance to deliver more efficient system thermal management. Optimal I/Q balance adjustment and minimal LO leakage results in improved EVM performance.

In addition to samples and evaluation kits (EVK) pSemi offers a complete support package of software tools and technical expertise to help customers get up to speed working with these mmWave beamformer ICs, up-down converter ICs, or arrayed combinations of both. Features include:

  1. A software GUI to ensure proper operation of register programming for effective, efficient code implementation.
  2. API integration to optimize performance across channels with GUI and API integration. Speed up software development and demonstration by embedding pSemi software within customer-specific code.
  3. Comprehensive user manual for each product that contains register programming requirements and operational details.
