  • Patent number: 9537516
    Abstract: The present invention is directed to a transmitter system. The system is made up of a reference clock, a differential oscillator and an edge combining power amplifier (ECPA). The clock feeds a low frequency reference signal into the differential oscillator to produce at least two low frequency outputs with opposite phases. Each low frequency output is made up of a number of low frequency subsignals equal to the number of oscillator stages. Each low frequency output is fed into a branch in the ECPA having a number of sub-branches equal to the number of oscillator stages. A processor uses an edge combining algorithm to combine these subsignals into a high frequency signal.
