Abstract: A diplexer may include a diplexer circuit unit including a first branch operating in a first frequency band and a second branch operating in a second frequency band, a static-electricity protection circuit unit connected to at least one of the first branch and the second branch in parallel so as to discharge static electricity flowing in the first or second branch toward an avoidance path, and a compensation circuit unit connected to at least one of the first branch and second branch so as to compensate for degradation caused by the static-electricity protection circuit unit.
