New Transceiver IC Eases mmW 5G Front End Design
Large 5G cellular wireless networks will rely on many small cells to reach subscribers with service at millimeter-wave (mmW) frequencies. Due to small wavelengths, mmW signals require many closely spaced cells to transmit and receive signals at frequencies above 24 GHz. Fortunately, a 5G small cell with multiband frequency coverage from 24.25 to 29.50 GHz (3GPP n258, n257, and n261) and intermediate frequency (IF) range from 4 to 10 GHz can be assembled with just two integrated circuits (ICs) from Anokiwave.
These ICs comprise a dual channel, transmit/receive frequency upconversion/downconversion transceiver IC paired with a dual quad 4x2 beamformer IC. Together they seamlessly enable the realization of dual polarized antennas in a single active array. The high integration and component density of these ICs speed and simplify the design and development of radio front ends for 5G small cells with the excellent power efficiency expected from an advanced silicon CMOS semiconductor process.
This whitepaper provides an overview of our latest IF transceiver IC together with our recently released 4th generation beamformer ICs, enabling new levels of integration and flexibility to develop 5G radios with significantly smaller size, lower cost, and higher power efficiency.
