摘要: Multistage RF transmitter and receiver circuits may use independently variable IF local oscillators, allowing the oscillator frequencies for a given channel to be selected have large common factor with respect reference used by circuits, thus of small divisor numbers in reducing phase noise. Independent high-side low-side oscillators provided selectively depending on transmitted or received.
