8-PSK Upconverting Transmitter Using E-band Frequency Sextupler
Journal article, 2018
Operation of a frequency sextupler (X6) as a radio frequency (RF) E-band upconverting transmitter is experimentally demonstrated. An 8-phase-shift keying signal is digitally upconverted to 13.1-GHz intermediate frequency (IF). The resulting signal then goes through the X6 resulting in IF-to-RF upconversion to 78.6 GHz without the need for high-frequency oscillator, mixer, or modulator. A simple one-sixth phase retardation of the baseband signal is used as digital predistortion. A full signal processing chain is implemented at the digital receiver. Techniques to mitigate remaining nonlinearity and worsened phase noise are considered.
