High frequency package, wiring board, and high frequency module

摘要

A high frequency package is arranged such that it comprises a dielectric substrate provided with an input terminal and an output terminal, a high frequency element mounted on the surface of the dielectric substrate, and a high frequency line formed on the dielectric substrate for connecting the high frequency element with the input terminal and with the output terminal, wherein a transmission characteristic from the input terminal to the output terminal has the property of cyclically varying in relation to frequency. The length of the high frequency line is regulated such that the frequency of signals transmitted along the high frequency line is located at a part of the cyclic variation curve of the transmission characteristic where transmittance is large. By arranging the structure in such a manner, loss of high frequency signals having frequencies of 10 GHz or more can be reduced.
