Abstract
A frequency converter has an active component acting both for amplification and for oscillation purposes. The converter transforms two signals of different frequencies into a signal of a third frequency. The two frequencies are supplied at different inputs. The two frequencies are mixed and the converter also has a positive feedback device connected to the second input. The amplification circuit (108) of the first and second signal feeds directly to the frequency mixer (110). The frequency mixer reflects any signals outside of the frequency band of the third frequency. The reflected signals are conducted to one output (121) whereas the positive feedback is connected to the other output terminal. The reflected signals are conducted to one output (121) whereas the positive feedback is connected to the other output terminal. The amplification and oscillation process of the amplifier takes place in the linear region.
