ABSTRACT:
A communication system includes a front-end multi-throw switch, a back-end multi-throw switch, multiple filters and a switch controller. The front-end multi-throw switch includes front-end throws and a front-end pole. The front-end pole is coupled to a receive channel or a transmit channel. The front-end pole is switchably coupled to one of the front-end throws. The back-end multi-throw switch includes back-end throws and a back-end pole. Each of the back-end throws is associated with a corresponding one of the front-end throws. The back-end pole is coupled to the receive channel or the transmit channel. The back-end pole is switchably coupled to one of the back-end throws. The one of the back-end throws corresponds to the one of the front-end throws. The filters are interposed between the front-end multi-throw switch and the back-end multi-throw switch. Each of the filters has a first port coupled to one of the front-end throws and a second port coupled to one of the back-end throws. A first one of the filters includes a filter of a first bandwidth. A second one of the filters includes a filter of a second bandwidth. The first bandwidth is different from the second bandwidth. The switch controller is coupled to the front-end multi-throw switch and the back-end multi-throw switch. The switch controller is configured to synchronously switch the front-end pole to one of the front-end throws and the back-end pole to a corresponding one of the back-end throws.
