Abstract
A limiter circuit includes: one or a plurality of first diodes having an anode electrically connected to a signal line through which a high-frequency signal passes, and a cathode electrically connected to a node, the plurality of first diodes being connected in series; a transistor having a source-drain path or an emitter-collector path electrically connected between a reference potential and the node, and a gate or a base to which a control voltage or a control current is input; and a first constant current source that outputs a first constant current to the node.
Claims7
A limiter circuit comprising:
- one or more first diodes connected in series, each first diode having an anode electrically connected to a signal line through which a high-frequency signal passes, and a cathode electrically connected to a node;
- a transistor having a source-drain path or an emitter-collector path electrically connected between a reference potential and the node, and a gate or a base to which a control voltage or a control current is input;
- and
- a first constant current source configured to output a first constant current to the node.
