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

摘要： An FSK modulator and applications thereof are disclosed. The FSK modulator comprises a phase-locked loop, a frequency divider module, an image rejection mixer and a summing module. The phase-locked loop is operably coupled to generate a first oscillation from a reference oscillation. The frequency divider module is operably coupled to divide the first oscillation to produce a second oscillation. The image-rejection mixer is operably coupled to mix the second oscillation with a low intermediate oscillation to produce a mixed data signal, and the summing module is operably coupled to sum the mixed data signal with the first oscillation to produce an FSK modulated signal.
