COMPOSITE HIGH-FREQUENCY COMPONENT

摘要

For example, a transmission/reception changeover switch (203) has a first diode (GD1) in series with a transmission signal path, has a second diode (GD2) in shunt with a reception signal path, and connects a first current path (GCR1) in which a DC current flows into the first diode (GD1) and a second current path (GCR2) in which the DC current flows into the second diode (GD2) in parallel. When a predetermined positive voltage is applied to a control terminal (VcG), the DC current flows through a control terminal (VcG) ? a resistance (GR) ? an inductor (GSL1) ? a diode (GD1) ? a strip line (Lt1) ? a strip line (Lt2) ? a shared inductor (Lt3) and the DC current flows through the control terminal (VcG) ? the resistance (GR) ? a diode (GD2) ? a strip line (GSL2) ? the strip lines (Lt1) ? (Lt2) ? the shared conductor (Lt3).
