First Claim
1. A repeater, comprising:
- a first interface port to communicate two or more signals that include multiple bands with one or more guard bands between the multiple bands;
a second interface port to communicate the two or more signals;
a dual-common port multi-bandpass filter communicatively coupled to the first interface port, the dual-common port multi-bandpass filter comprising;
a first common port coupled to the first interface port and an input to each of two or more analog filters in the dual-common port multi-bandpass filter, wherein each analog filter in the dual-common port multi-bandpass filter is configured to filter one or more bands in the two or more signals; and
a second common port coupled to the second interface port and an output of each of the two or more analog filters in the dual-common port multi-bandpass filter; and
an amplifier communicatively coupled between the first interface port and the second interface port.

Abstract
A technology for a dual-common port multi-bandpass filter is described. The dual-common port multi-bandpass filter can include two or more analog filters. The dual-common port multi-bandpass filter can include a first common port coupled to an input of each of the two or more analog filters. Each analog filter can be configured to filter one or more frequency bands. The dual-common port multi-bandpass filter can include a second common port coupled to an output of each of the two or more analog filters. Each input of each of the two or more analog filters is impedance matched with the first common port. Each output of each of the two or more analog filters is impedance matched with the second common port.
