Designing a transmit/receive earth station for X-Band poses problems due to the fact that the transmit and receive bands are separated by only 150MHz. The top of the receive band is 7.75GHz, while the bottom of the uplink band is 7.9GHz. This implies that sophisticated filtering is required. Couple this with the ability to handle transmit powers of maybe 10kW and one can see that a realistic, viable design is not an easy nut to crack. Adding the fact that 10kW klystrons only have a usable bandwidth of maybe 170MHz at X-Band means that a low loss combining network is required. Here's an "out-of-the-box" way to solve these problems.

Before diving straight into the design, have a look at the true, humourous story surrounding the paper "Design of a High Power Earth Station Transmitter for the Band 7.9 to 8.4 GHz" I wrote ages ago, here. There's a link to the paper in the story. Enjoy!
