The ECLIPSE3741 from Sivers Semiconductors is a 5G Beamformer Phased Array Antenna-in-Package (AiP) module that operates from 37 to 41 GHz covering the 5G FR2 n260 band. It is designed for 5G mm-Wave wireless infrastructure systems to enable easier implementation, lower cost, compact solution, and a higher data rate. This AiP module consists of 16 antenna array elements to ensure directionality. It integrates Tx/Rx RF chains that perform efficient TDD-based beamforming in independent directions and incorporates low-loss Tx/Rx switches enabling them for TDD applications. The module consumes 10.24 W of power in the Tx chain and 640 mW in the Rx chain per polarization.
The ECLIPSE3741 delivers an EIRP of +45 dBm (at 3% EVM) across the entire bandwidth and supports a 64-QAM modulation scheme with OFDM. It has been designed to provide half-wavelength lattice spacing when tiled together, thereby supporting high EIRP applications. It uses 6 bits to digitally phase shift the antenna elements across full 360° with 11.25° step size while offering a 15 dB variable gain range per path. This module is fully calibrated for gain/phase matching from channel-to-channel and chip-to-chip, including the antenna. It is also equipped with built-in temperature and power sensors (for each Tx path) to monitor, sense, and report any abnormal conditions in the design.
This AiP is available in a BGA module that measures 15 x 15 mm and is ideal for use in cellular base stations (gNodeB), consumer premises equipment (CPE), mobile user equipment (UE), and fixed wireless access (FWA) applications.
