Outphasing, Envelope, And Doherty Transmitter Test And Measurement

Meeting the requirements for energy efficiency of RF frontends can become challenging at high operating frequencies and bandwidths, such as those proposed for 5G. A solution is a group of transmitter RFFE architectures whose signal output is constructed from two or more efficiently generated components is put in effect to enable distortion to be completely eliminated. This application note focuses on the capabilities of multi-channel signal synthesis setups within the R&S®SMW200A, in combination with the R&S®FSW analyzer to enable measurement and development of energy efficient frontends.
