Abstract
A common-direction duplexer may include a common port, a first-band port, and a second-band port. The common-direction duplexer may also include a first filter between the common port and the first-band port. The first filter may be configured to pass a first frequency range and filter out a second frequency range and a third frequency range. The first and second frequency ranges may be associated with a first-direction signal transmitted in the first and/or second frequency range. The third frequency range may be spectrally between the first and second frequency ranges and may be associated with a second-direction signal that propagates in a direction opposite that of the first-direction signal. The common-direction duplexer may also include a second filter between the common port and the second-band port. The second filter may be configured to pass the second frequency range and filter out the first and third frequency ranges.
