High frequency package, wiring board, and high frequency module having a cyclically varying transmission characteristic

A high frequency module comprising at least one high frequency package mounted on a wiring board, each high frequency package comprising:

• 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 disposed 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, and the frequency of signals transmitted along the high frequency line corresponds to that at a part of the cyclic variation curve of the transmission characteristic where transmittance is large.

A high frequency module comprising at least two high frequency packages and a wiring board, each of the high frequency packages comprising:

• 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 first high frequency line disposed 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, and the frequency of signals transmitted along the first high frequency line corresponds to that at a part of the cyclic variation curve of the transmission characteristic where transmittance is large, and
• a transmission characteristic from one terminal portion to the other terminal portion on a second high frequency line connecting the two high frequency packages on the wiring board has the property of cyclically varying in relation to frequency, and the frequency of signals transmitted along the second high frequency line corresponds to that at a part of the cyclic variation curve of the transmission characteristic where transmittance is large.
