<p>PROBLEM TO BE SOLVED: To provide superconducting filters adopting a flat transmission line structure that has a sufficient S/N without causing no interference even when they are placed close to each other and that has an excellent cooling efficiency without sacrificing the compactness that is a feature of the flat transmission line structure. SOLUTION: The wireless transmitter-receiver is provided with a superconducting reception filter (2) adopting the flat transmission line structure that selects signals received from an antenna and with a superconducting transmission filter (1) adopting the planar transmission line structure that selects signals to be sent to the antenna, which are contained in a heat insulation package spaced at an interval of nearly a wavelength of a transmission signal. The components, resonance elements (22) and signal input output lines (21, 23) of the reception filter (2) and the components, resonance elements (12) and signal input output lines (11, 13) of the transmission filter (1) are placed not in parallel with each other.</p> |
