Abstract

See full text

A wireless radio-frequency transmission apparatus includes a phase frequency detector, a charge pump, a loop filter and a twin voltage-controlled oscillator. The twin voltage-controlled oscillator includes a first oscillator and a second oscillator. When the twin voltage-controlled oscillator is in a reception mode, the first and the second oscillators are coupled to each other to form a quadrature voltage-controlled oscillator, and the quadrature voltage-controlled oscillator, the phase frequency detector, the charge pump and the loop filter constitute a phase-locked loop to generate quadrature carriers. When the twin voltage-controlled oscillator is in a transmission mode, the first oscillator, the phase frequency detector, the charge pump and the loop filter constitute a phase-locked loop, and the second oscillator performs frequency modulation on transmitted data. The present disclosure can maintain a carrier frequency to be stable during high data rate transmission, and have a relatively short locking time of frequency hopping.
