This paper deals with a study on multiplexer topology based on 3dB couplers. A diplexer in Ku-band was conceived and printed using material jetting (Polyjet®) and Fused Deposition Modeling (FDM) technologies for this purpose. The different parts composing the diplexer are separately tested. In a first step, 3 dB directional couplers are printed with both technologies experimentally confirming the...
This paper introduces a new concept capable of obtaining a wide frequency excursion, keeping high electrical performances. To reach such performances, the use of waveguide resonators is chosen, actuated by a mechanical system is made. Starting from a classical 2 pole E-plane filter, which consists of thin walls implemented along the propagation axis inside a waveguide, we make both the filter external...
