PROBLEM TO BE SOLVED: To provide an isolator module that compactly has a simple circuit configuration and can implement a multiband high frequency circuit section or a balanced amplifier together with amplifiers.SOLUTION: The isolator module comprises: central conductors 30 disposed on microwave ferrite members 70; a permanent magnet for applying a bias magnetic field to the microwave ferrite members 70; and input ports P1in, P2in and output ports P1out, P2out for inputting/outputting high frequency signals, and has a first resonance circuit between the input port P1in and the output port P1out, a second resonance circuit between the output port P1out and a ground, a third resonance circuit between the input port P2in and the output port P2out, and a fourth resonance circuit between the output port P2out and the ground. The second resonance circuit and the fourth resonance circuit are connected to the ground via an inductance element Lc1. |
