Title:
ADAPTIVE IMPEDANCE MATCHING NETWORK
Document Type and Number:
Japanese Patent JP2016006997
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an adjustable matching impedance.SOLUTION: A matching network includes first and second impedance adjusting means 10, 12. The first impedance adjusting means is adapted to adjust the value of an imaginary part of the matching impedance while substantially maintaining the value of the real part of the matching impedance on the basis of frequency information frequency and a target reference value. The second impedance adjusting means is adapted to adjust the value of the imaginary part of the matching impedance to be substantially equal to zero on the basis of the frequency information, so as to adjust the real part of the matching impedance to be substantially equal to the target reference value.
