This unit basically consists of two parts: SSB-Generator and TX-mixer TX-power amplifier stages The SSB-Generator and TX-Mixer Board After having built this respective board with two NE612 ICs (one for DSB generator, one for the TX mixer) I was not satisfied with carrier suppression of the DSB generator. It turned out as only 40dB. Afterwards…
The first power amplifier for this transceiver project initially was capable to produce 20 watts of SSB pep rf power on the 20 meter band. The transistors in use are the 2SC1969 bipolar types by eleflow.com. A single device is rated to max. output power of 16 watts according to data sheet. In push-pull mode…
