Title:
チューナブル整合回路
Document Type and Number:
Japanese Patent JP2004524778
Kind Code:
A
Abstract:
The present invention quantifies and reduces losses in tunable bandpass filters having ferro-electric capacitors. Given a required insertion loss and the quality factor of a resonator, the geometric losses resulting from a particular topology for the ferro-electric capacitor and the metal losses are accounted for to quantify the allowable ferro-electric losses.
