Abstract
A variable capacity composite component has structures connecting four variable capacitors, for example, to signal terminals in series with bias application terminals of opposite polarities facing each other, connecting a power supply terminal to the bias+ sides of the first and second variable capacitors via a first bias resistance, and also to the bias+ sides of the third and fourth variable capacitors via a second bias resistance, connecting a grounding terminal to the bias− side of the first variable capacitor via a third bias resistance, also to the bias− sides of the second and third variable capacitors via a fourth bias resistance, and also to the bias−sides of the fourth variable capacitor via a fifth bias resistance, and setting the value of the first, second, and fourth bias resistances to one-half the value of the third and fifth bias resistances.
