In 5G FR2 mmWave application scenario, HB focuses on open-RAN (ORAN) topology and plays a role in Fixed Wireless Access(FWA) solution. We developed an 28GHz antenna on package(AoP) with SIVERS beamforming IC, peripheral circuitry and specified patch antenna array. HB could customize beamforming IC solution, antenna design/arrangement and substrate material for customer demands.
