pSemi’s David Watling demonstrated the company’s eight-channel beamforming ICs for RF engineers.

Beamforming, also called beam steering, is one of the features at 5G that should bring mmWave and it’s wide signal bandwidth to the masses. pSemi, one of several semiconductor companies in the beamforming business, demonstrated its eight-channel Beamforming Front End, the PE188100 and the PE188200. Both devices cover mmWave frequencies with the PE188100 covering 24.25 GHz to 27.5 GHz and the PE188200 covering 26.5 GHz to 29.5 GHz.

In the video, pSemi’s David Watling explains how the devices steer beams on a 4&times4 antenna array by changing the signal’s phase. Each of the ICs supports eight channels, four using horizontal polarization and four using vertical polarization.
