PROBLEM TO BE SOLVED: To provide an unbalanced type filter with wide bandwidth. SOLUTION: A balanced circuit 81 is a 2 terminal pair circuit network, and includes the 1st and the 2nd input and output terminals Vin1, Vin2, Vout1, and Vout2. An unbalanced circuit is a 2 terminal pair circuit network, and includes the 3rd and the 4th input and output terminals Vin3, Vin4, Vout3, and Vout4. The 2nd input terminal Vin2 is connected to the 3rd input terminal Vin3. The 2nd output terminal Vout2 is connected to the 3rd output terminal Vout3. The 1st input terminal Vin1 and the 4th input terminal Vin4 are filter input terminals V1, V2. The 1st output terminal Vout1 and the 4th output terminal Vout4 are filter output terminals V3, V4.
