A recent video from [W2AEW] shows how this works and also how AM can be made more efficient by stripping the carrier and one sideband using SSB or single sideband modulation.

The MBC-IQ-Lab is an electronic system able to control MXIQER modulators in a CS-SSB modulation scheme. It is based on the minimisation of the beating harmonic of two small dithers. This system ...

The LT5528 is a direct I-Q modulator incorporating a matched pair of double-balanced mixers that form a carrier suppressed, image reject I-Q (In phase and quadrature) modulator. It is intended for ...
