MULTIBAND TRANSMITTER CIRCUIT WITH INTEGRATED CIRCULATORS AND FILTERS |
摘要 |
A multi-band transmitter circuit may include a multi-port network configured to divide an input multi-band signal comprising signal components at each of a plurality of frequency bands into a plurality of output multi-band signals. The multi-band transmitter circuit may also include a plurality of band-specific circulator paths. Each band-specific circulator path includes a circulator configured to receive the respective output multi-band signal and operate at a respective one of the frequency bands to provide a respective band-specific signal. The multi- band transmitter circuit further includes a filter circuit that includes a plurality of band-specific filter elements. Each band-specific filter element is coupled to a corresponding circulator and configured to receive the respective band-specific signal and operate at the same frequency band as the corresponding circulator to provide a filtered band-specific signal for transmission. |
