Title:
HIGH FREQUENCY SWITCH AND ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/207836
Kind Code:
A1
Abstract:
A reactance SW 30 is inserted between an interface 10 and an output interface 20. The reactance SW 30 includes: a first reactance circuit 31 having, for example, a fixed pass band; and a second reactance circuit 33 the pass band of which is changed by a change in reactance. When an ON state is set, the pass bands of the first reactance circuit 31 and the second reactance circuit 33 are made identical. In this way, a high-frequency signal input into the input interface 10 is guided to the output interface 20. On the other hand, when an OFF state is set, the reactance of the second reactance circuit 33 is changed to reflect a high-frequency signal that has passed through the first reactance circuit 31.
