A circuit includes a first system-on-chip (SoC) driven by a first clock generator and a second SoC driven by a second clock generator where the first clock generator and the second clock generator have independent time bases. The first and second clock generators are synchronized using an RLC circuit external to the first clock generator and the second clock generator that converts an output of the first clock generator into current pulses and injects the current pulses into the second clock generator to pull an output of the second clock generator into synchronization with the output of the first clock generator. The RLC circuit converts a voltage output of the first clock generator into current pulses at the resonant frequency or specific harmonics of the output of the first clock generator. The second clock generator may include a ring oscillator into which the current pulses are injected.

The present embodiments are directed to a device for generating radio frequency signals, including high power radio frequency signals. In certain embodiments, the device comprises multiple transmission lines driven in parallel at their input and connected in series at their output. The electromagnetic transit lengths of the transmission lines may be unequal. A series connection of the transmission lines at the output may produce an output signal from each transmission line driving the same polarity signal to the load. The series connection of transmission lines at the output may produce a bipolar output signal. One section of the device may convert a unipolar input signal into a bipolar signal. One section of the device may duplicate the input signal. Multiple sections may be arranged to convert a unipolar input signal into multiple radio frequency oscillations.
