Abstract
A transmitter upconverts a SSB data signal during a first operational mode using a RF upconverting signal having a frequency that is offset from a center frequency of a channel (ω) by an amount that depends on the data signal's SSB bandwidth (ω). In a second operational mode, the transmitter upconverts a tone signal having a frequency ωusing the same RF upconverting signal. The upconverted tone signal can be used as a continuous wave (CW) carrier signal having a frequency ω. The transmitter has a single RF oscillator to output both a SSB signal centered at frequency ωduring the first mode and a carrier signal of frequency ωduring the second mode.
