pSemi® Corporation, a Murata company focused on semiconductor integration, announces the expansion of its millimeter wave (mmWave) RF front-end portfolio for 5G wireless infrastructure applications. The new pin-to-pin compatible products, including three beamforming ICs and two up-down converters, offer flexibility to interchange ICs for full IF-to-RF coverage across the n257, n258 and n260 bands. This modular approach, combined with on-chip calibration and digital correction, allows system teams to simplify their design cycles and quickly adapt to different active antenna design configurations. Available as discrete RFICs or as part of the Murata 28 GHz antenna-integrated module, this diverse portfolio delivers performance, integration and reliability in the smallest IC form factor.

mmWave will reach mainstream deployments first in dense urban areas that benefit from short-range coverage supported by smart repeaters, indoor base stations and other small-cell applications. This increased demand for network capacity, along with the proliferation of beamforming and active antenna systems, has opened new doors for SOI-CMOS technology as the preferred mmWave platform for advanced 5G systems.
“pSemi has offered mmWave products since 2015, deepening our expertise and patent portfolio in high-frequency RF SOI design,” says Vikas Choudhary, vice president of sales and marketing at pSemi. “This history—combined with the advanced packaging and global manufacturing strength of our parent company, Murata—enables us to support higher levels of integration to simplify 5G mmWave development and deployment.”
8-channel Beamformer RFIC Features & Benefits
Each PE188100, PE188200 and PE189100 RFIC integrates power amplifiers (PA), low-noise amplifiers (LNA), phase shifters and switches into a single die that provides optimal signal strength for up to 1024-element antenna arrays.
Full spectrum coverage – n257 (PE188200), n258 (PE188100) and n260 (PE189100) band support and pin-to-pin compatibility
Flexible antenna design – Eight independently controllable RF channels with support for four dual-polarized or eight single-polarity antenna elements
Beamforming accuracy – Linear POUT at the desired EVM with low RMS phase and amplitude error for increased array gain and antenna directivity
Dual-channel Up-down Converter RFIC Features & Benefits
Each PE128300 and PE129100 RFIC integrates frequency multipliers, quadrature mixers, amplifiers and switches into a single die that can be paired with up to 16 pSemi beamforming RFICs, or 128 total beamformer channels, to support massive-MIMO, hybrid-beamforming and other active antenna configurations.
