Abstract
A frequency modulator includes a first pair of diodes with two capacity diodes, and a second pair of diodes with two additional capacity diodes. The second pair of diodes is employed in parallel. The frequency modulator also includes a first modulator input for reception of a first modulation signal and a second modulator input for reception of a symmetrical second modulation signal. Both pairs of diodes are coupled to an oscillator unit.
