I am constantly on the lookout for effective yet inexpensive means to generate SSB signals. Analog Devices' LTC5598 Direct Quadrature Modulator turns baseband analog I/Q signals into RF from 5MHz to 1.6GHz. Sadly, the performance falls off dramatically for the amateur radio bands below 60 meters.
What would happen, theoretically, if the output of the LTC5598 could be processed through some frequency-dividing means to cover lower frequencies? Would the spectrum of the modulation be preserved, distorted or destroyed?
