To fulfill the demand of cellular communication with faster data speed, 5G enables mmWave, along with conventional sub-6GHz, to accommodate the need of wider bandwidth. TSMC offers comprehensive and competitive RF technology options to cover the entire spectrum. For sub-6GHz products, TSMC provides RFCMOS and Silicon on Isolator (SOI) technologies for transceivers (TRx) and front-end module (FEM), respectively. On the mmWave spectrum, RFCMOS meets both intermediate-frequency TRx and mmWave FEM.
