Abstract:
Aspects of a method and system for frequency control in a frequency shifting repeater are provided. In this regard, a reference frequency may be divided to generate a first pair of local oscillator (LO) signals, the first pair of LO signals may be divided to generate a second pair of LO signals. The two pairs of LO signals may be utilized to frequency shift a received signal for repeating the signal on a different frequency. The frequency shifted signal may be generated by down-converting the received signal utilizing the first pair of LO signals, up-converting the down-converted signal utilizing the second pair of LO signals, and combining the resulting up-converted signals. The reference frequency may be divided by a first scaling factor to generate the first pair of LO signal which, in turn, may be divided by a second scaling factor to generate the second pair of LO signals.
