Sivers Semiconductors AB has announced the commercial launch of its BFM02803 state-of-the-art new low-cost RF module for FWA applications, covering the 5G FR2 mmWave bands N257, N258, and N261 (from 24.25 GHz to 29.5 GHz).

The 5G mmWave module — launched at Mobile World Congress 2024 — is optimized for high-performance, high-power Fixed Wireless Access (FWA) applications and meets the requirements of large-scale manufacturing of FWA products. It is designed to interface with leading baseband modems and enables manufacturers to differentiate their 28 GHz FWA products.

The BFM02803 supports 2×2 MIMO with dual-layer polarization in both downlink and uplink for channels up to 1.2 GHz. The new module includes 32 dual-polarized antenna elements with 2D beam steering capabilities, in azimuth and elevation.

Anders Storm, Group CEO of Sivers Semiconductors commented: “Sivers Semiconductors pushes ahead with even more 5G innovations. By combining the market-leading performance of the TRB02801 RFIC with innovative antenna design, you get the flexibility and performance required for large deployments of 28 GHz FWA networks.”

Autonomous calibration routines and simple baseband interfaces make the module easy to install and manage. With the use of an air-filled cavity in the PCB, the module is optimized for large-scale, low-loss, and low-cost assembly. Additionally, transmitted power greater than +50 dBm per polarization enables FWA product deployments in the most diverse applications with the lowest total cost of ownership.

Anders Storm continues: “This module will improve your business case and make your 28 GHz fixed wireless access product truly competitive.”

The BMF02803 module will be showcased in a live demonstration of a fully-functioning and deployment-ready base station reference design based on NXP’s Layerscape® Access LA12xx baseband processor, the TRB02801 5G mmWave transceiver module from Sivers Semiconductor, and PureSoftware’s physical layer stack.
