HIGH SPEED DATA TRANSMITTER

摘要

Data transmitters are known which are essentially linear amplifiers designed for single side band suppressed carrier mode of operation and while these are suitable for voice and single tone keyed transmission, they are less satisfactory for multi-tone transmissions because the transmitter peak power handling capability limits the average output power per tone. The present invention enables high average power per tone in a multi-tone transmitting system. A plurality of means are provided for generating RF tones. The tone modulated RF signals are then combined to form a single resultant modulated RF signal and the resultant RF signal is fed to an antenna.
