| titleOfInvention | Microwave duplexer and manufacturing method thereof |
| abstract | The present invention is a high temperature superconducting subsystem incorporating a microstrip branch line type 3dB hybrid coupler and a parallel couple line type 2 pole bandpass filter as part of a multi-channel multiplexer, which is a key component used in a microwave communication system. The microstrip high temperature superconducting microwave duplexer is implemented through high temperature superconducting YBCO / MgO epitaxial thin film and micro shaping process, and the filter signal at the output port has 11GHz center frequency. On the other hand, a high-temperature superconducting duplexer was built in a four-port type three-component test fixture, and a double metal electrode and a ground plate were deposited on an electron beam evaporator on the front and back of the substrate for measuring low-temperature microwave characteristics. Therefore, the high temperature superconducting duplexer has an Au / Ti / YBCO / MgO / Ti / Ag structure. These high-temperature superconducting duplexers are lossless, dissipative and signal-processing for wireless and microwave communications components. Microstrip-based subsystems make manufacturing simple, lightweight, and most suitable for equipment such as PLDs. The design is also expected to accelerate the development of high-temperature superconducting MMICs. |
