ABSTRACT:
A phase adjusting circuit includes a meandering inductor provided on the surface of a base substrate, and a zero-ohm resistor mounted on two parallel line portions with one parallel line portion provided therebetween. The parallel line portions of the meandering inductor are configured such that their lengths in the vertical direction sequentially decrease. By changing a combination of parallel line portions on which the zero-ohm resistor is mounted, the substantial line length of the inductor is changed, such that the inductance changes. By changing the inductance of the inductor, the amount of phase adjustment in the phase adjusting circuit is changed.
