<p>In embodiments of the present invention, an antenna front end (100,200) includes at least two diplexers (110, 120, 210, 220). 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 (115, 215), a receive band filter (140A, 140B, 240A, 240B) and a transmit band filter (130A, 130B, 230A, 230B), which are adjoined and matched to form a continuous waveguide channel. Some embodiments further include a transmit hybrid coupler (150, 250) and/or a receive hybrid coupler (160, 260). 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.</p> |
