Abstract
In some embodiments of the present invention, an antenna front end includes at least two diplexers. Each of the diplexers is defined with a channel within a single material block. Each channel is shaped to provide a diplexer which includes a coupler, a receive band filter and a transmit band filter, which are adjoined and matched to form a continuous waveguide channel. Some embodiments further include a transmit hybrid coupler and/or a receive hybrid coupler. The transmit hybrid coupler is formed as a channel within the material block and adjoined and matched to the two transmit band filters. The receive hybrid coupler is formed as a channel within the material block and adjoined and matched to the two receive band filters.
