“Gimme Five” reloaded – A compact 5 band QRP SSB transceiver in SMD technology – TRANSMITTER spectrum analysis

Abstract The 10 watts peak envelope power linear transmitter for single sideband operation will be examined. Test conditions are: 10 watt pep on every band, rf line terminated with 50 ohm dummy load, input audio two-tone signal identically applied for each measurement. Measurements have been taken with RIGOL DSA815 spectrum analyzer, RIGOL DS1054 digital oscilloscope…
