Differential front-end design presents a good prospect to be integrated with differential beamformer inputs without a transformer needed otherwise for a single-ended front-end design. A front-end solution with a complete differential configuration is presented. The potential advantages of this design are: planar antenna elements mean a lower cost; differential LNAs in close proximity to the antenna elements reducing feedline loss hence potentially a low noise figure and a less power consumption without an active balun needed in the RF signal chain.
