DUEL MODE 5-POLAR BAND PASS FILTER AND THE MANUFACTURING METHOD OF X-BAND RING TYPE DEGREE SUPERCONDUCTIVITY

摘要

The present invention is a perturbation semi-ring type high temperature superconducting double for X-band that allows information to pass only in a specific frequency band, which is a core element that constitutes a core component such as a multiplexer and a mixer used in an RF and microwave communication system or a communication device. A mode 5-pole bandpass filter, comprising: a MaO single crystal substrate having excellent RF and microwave characteristics, a signal transmission input / output terminal (including a gold pad) formed at one corner of an upper portion of the single crystal substrate, and the input / output terminal above the single crystal substrate; A circuit pattern of two perturbation semicircular resonators for controlling or filtering the transmission energy of the signal between the microstrip coupling lines and the ring-shaped high-temperature superconducting dual mode 5-pole bandpass filter integrating the microstrip coupling lines, and a lower portion of the single crystal substrate. Ring type high temperature composed of deposited metal thin film for ground plane The number of poles of the conduction dual mode bandpass filter is 5-pole, and the size of the circuit pattern is within 15 mm x 15 mm in consideration of the size of the substrate. The microwave characteristics are excellent in flatness even in the pulse width amplitude in the pass band. It is also excellent in the steep skirt characteristic to the stop band.
