| 摘要 |
An arrangement for tuning a receiver over two or more frequency ranges comprising at least two interconnected variable capacity systems. Each system comprises at least first and second capacitor elements, means for connecting in parallel respective first capacitors of the two systems together to form a composite variable capacitor for tuning within one of the frequency ranges, and means for connecting respective second capacitors of the two systems together to form a composite variable capacitor for tuning within the second of the frequency ranges.
