The invention concerns a device for combining varactors for control of an oscillator. For control of an oscillator there is a need to allow the frequency to sweep over a wide range and also to lock the middle frequency or fine-tune the oscillator to a station. According to the invention two varactors V are combined with a hybrid circuit 4. By this means the oscillator is provided with two control inputs IL, IM with different sensitivity. One control input controls the sweep of the wide range while the second input controls the locking frequency. <IMAGE> |
