Patent ID: 7486157

Claim:
A package for high frequency waves comprising: an box-shaped high frequency package containing a high frequency electronic circuit in the inside and shielded by a conductor; an input terminal and an output terminal partly led out to the outside of the high frequency package; and an input side feed-through section and an output side feed-through section arranged to respectively connect the input terminal and the output terminal to the high frequency electronic circuit mounted in the high frequency package, maintaining an hermetic condition, each of the input side feed-through section and the output side feed-through section having a first micro-strip line connected to the high frequency circuit, a second micro-strip line connected to the output terminal and the input terminal and a feed-through line connecting the first and second micro-strip lines, maintaining an hermetic condition for them; the line width of the output terminal side feed-through line and those of the first and second micro-strip lines being increased so as to obtain a required current capacity within a range allowable for matching with the high frequency electronic circuit.
