5G designs that use wide-bandwidth digital modulation require new test technologies. Our latest 5G whitepaper presents a testbed for generating and analyzing millimeter-wave signals with 8 GHz bandwidth. We used it to generate V- and E-band signals and apply digital pre-distortion (DPD) algorithms, achieving impressive improvements in ACPR and EVM.
