Independent dual single-sideband vector millimeter-wave signal generation by one single I/Q modulator

We propose a new scheme to realize the independent dual single-sideband (SSB) vector millimeter-wave (mm-wave) signal generation based on one single in-phase/quadrature (I/Q) modulator. The two SSB vector mm-wave signals can have independent carrier frequencies and modulation formats. We experimenta...

Description
Summary:We propose a new scheme to realize the independent dual single-sideband (SSB) vector millimeter-wave (mm-wave) signal generation based on one single in-phase/quadrature (I/Q) modulator. The two SSB vector mm-wave signals can have independent carrier frequencies and modulation formats. We experimentally demonstrate the simultaneous generation and transmission of 38 GHz 16-ary quadrature-amplitude-modulation (16QAM) and 40 GHz quadrature-phase-shift-keying (QPSK) mm-wave signals based on this scheme. The penalty of the 16QAM and QPSK mm-wave signals after transmission over 10-km standard single-mode fiber and 0.5-m wireless link can be neglected.
