Single Sideband Frequency Conversion Systems
In many instances the band of sideband frequencies generated by a low level SSB transmitter must be heterodyned up to the desired carrier frequency. In receivers the circuits which perform this function are called converters or mixers. In sideband work they are usually termed mixers or modulators.
Mixer Stages One circuit which can be used for this purpose employs a receiving-type mixer tube, such as the 6BE6. The output signal from the SSB generator is fed into the #1 grid and the conversion fre-
