Abstract
PURPOSE:To prevent the occurrence of a fault due to higher harmonic distortion, by inverting the polarity of a varactor diode at every stage by turns. CONSTITUTION:Diodes 11a-11n are inverted in polarity by turns and respective cold end sides are grounded individually via capacitors 12a-12n. Connection points between anodes of alternate diodes 11a, 11c-11n-1 and capacitors 12a, 12c-12n-1 are connected together via resistors 21a, 21<c>-21n-1 and the connection point is connected to bias terminal 223. Further, connection points between cathodes of diodes 11b-11n and capacitors 12b-12n are connected together via resistors 21b-21n, and this connection point is connected to bias terminal 22b. The voltage of terminal 20 is fixed and two control voltages varying reciprocally centering on the fixed voltage are supplied to terminals 22a and 22b to control the capacity value, so that desired phase-shifting extent can be obtained.
