Summary:PROBLEM TO BE SOLVED: To provide a high frequency circuit that achieves high performance compactly in a simple circuit configuration using a balanced amplifier and a balanced input/balanced output isolator module.SOLUTION: A pair of unit amplifiers PA1, PA2 are connected to a 90° hybrid circuit 5a. The first unit amplifier PA1 is connected to a first balanced input port Pi1 of a balanced input/balanced output isolator module 10 via a 90° phase shifter 30a, and the second unit amplifier PA2 is connected to a second balanced input port Pi2 of the balanced input/balanced output isolator module 10, to whereby input differential signals into the balanced input/balanced output isolator module 10.
