Original document(15 pages)  中文版
    An appparatus for radio frequency processing includes a local oscillator synthesizer circuit having a voltage controlled oscillator that generates an oscillator signal f1. A divide-by-N circuit receives the oscillator circuit f1 and divdes that signal to produce an f1/N oscillator signal. A dual modulus synthesizer is connected to the divide-by-N circuit and generates a quadrature modulus signal f1/N. A receiver circuit and a transmitter circuit are operatively connected to the local oscillator synthesizer circuit. Each of the receiver circuits and transmitter circuits has at least two mixer circuits for mixing and respectively down converting/up converting intermediate radio frequency singals.
