Abstract: Disclosed herein is a bias tee circuit connected between a common terminal and power supply and signal terminals, the bias tee circuit includes a capacitor inserted between the common terminal and the signal terminal, and first and second inductors inserted in series between the common terminal and the power supply terminal. The first inductor is connected on a side of the common terminal. The second inductor is connected on a side of the power supply terminal. The second inductor is higher in self-resonance frequency and lower in Q value than the first inductor.
