Tunable ferro-electric filter |
| 摘要 |
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.
