MMIC INTEGRATED MODULE

摘要

PROBLEM TO BE SOLVED: To improve radiation efficiency of a radio wave.SOLUTION: A metallic reflection plate 12 is formed on a bottom surface of a small cavity 7' so as to be opposite an antenna 10 of an MMIC chip 2. A plurality of veers 8 are formed so as to surround the reflection plate 12 and furthermore, a plurality of balls 9 for a junction are formed so as to surround the antenna 10.
