SWITCHING CIRCUIT AND HIGH-FREQUENCY MODULE

摘要

PROBLEM TO BE SOLVED: To provide a switching circuit that is almost free from the influence of a resonance frequency and allows preventing variation in isolation characteristics, and to provide a high-frequency module including the switching circuit.SOLUTION: A switching circuit 10 includes a first input/output terminal T1, a second input/output terminal T2, a third input/output terminal T3, a first transistor 11, a second transistor 12, an inductor 14, and a resistor 16. The first transistor 11 is electrically connected between the first input/output terminal T1 and the second input/output terminal T2. The second transistor 12 is electrically connected between the first input/output terminal T1 and the third input/output terminal T3. The inductor 14 and the resistor 16 are electrically connected in series between the second input/output terminal T2 and the third input/output terminal T3.
