Abstract
A 32-GHz (Ka-band) breadboard has been developed to demonstrate M-ary phase-shift keyed (PSK) and M-ary quadrature amplitude modulation (QAM) Ka-band modulations using a ×3 8-GHz (X-band) architecture. This breadboard consists of an X-band vector modulator that is driven by a field programmable gate array. The signal is mixed with an upconverted 24-GHz signal to give the Ka-band modulated output. Data rates from 650 kb/s to 130 Mb/s have been demonstrated with quadrature PSK (QPSK) and 16-QAM modulation formats.
