摘要： Provided are a terahertz wave transmission and reception (Tx/Rx) module package and method of manufacturing the same. The complete and separate terahertz wave Tx/Rx module package is implemented by simply aligning a silicon ball lens, a photoconductive antenna and a focusing lens, and thus facilitates generation or measurement of a terahertz wave. The terahertz wave Tx/Rx module package and method can remarkably reduce time and cost required to build a terahertz wave generation and measurement system, and simplify and miniaturize the terahertz wave generation and measurement system. In addition, characteristics of a terahertz wave generated by the photoconductive antenna can be simply measured. Furthermore, the terahertz wave Tx/Rx module package can be stored and transported with a photoconductive antenna, a silicon ball lens and a focusing lens kept aligned as they are, and also it is possible to minimize pollution of terahertz wave devices caused by surroundings.

摘要： Disclosed is a high-temperature superconductor low-pass filter for removing broadband harmonics in a wireless communication system. The high-temperature superconductor low-pass filter includes a coupled line section and a transmission line section, in which the coupled line section is connected in parallel with the transmission line section. The coupled line section has two microstrip open-stub type parallel stripe lines stacked on a high-temperature superconductor, and the transmission line section has one stripe line. Since the high-temperature superconductor low-pass filter has attenuation poles at a stopband, it has stopband characteristics to 7-8 times wider than a cutoff frequency. The high-temperature superconductor low-pass filter can easily remove sub-harmonics which are inevitably occurred in the wireless communication system.
