Abstract:
1. A local oscillator (LO) circuit for facilitating repeating of a signal transmitted from a first station on a first frequency channel to a second station on a second frequency channel in a frequency translating repeater operating according to a wireless protocol, the LO circuit comprising: a first tunable LO associated with the first frequency channel, the first tunable LO tunable in a first frequency range lower than the frequency of the first frequency channel; a second tunable LO associated with the second frequency channel, the second tunable LO tunable in a second frequency range higher than the frequency of the second frequency channel, the second frequency range different from the first frequency range; and a first converter circuit for down-converting the signal on the first frequency channel to a first intermediate signal having a first intermediate frequency, the down-converting using a first down-conversion mixer coupled to the first tunable LO, and for down-converting the signal on the second frequency channel to a second intermediate signal having a second intermediate frequency, the down-converting using a second down-conversion mixer coupled to the second tunable LO.
