Patent ID: 8884691

Claim:
A demodulator, comprising: a splitting/matching section for carrying out a matching process of making an amplitude and phase of a first modulated signal match respectively an amplitude and phase of a second modulated signal, wherein said splitting/matching section including: a splitting section, a first matching section for receiving said first modulated signal from said splitting section at a first input impedance determined by first predetermined circuit-element constants of said first matching section, and a second matching section for receiving said second modulated signal from said splitting section at a second input impedance determined by second predetermined circuit-element constants of said second matching section, said first circuit-element constants determining said first input impedance of said first matching section and said second circuit-element constants determining said second input impedance of said second matching section are set at predetermined values, wherein individual ones of said first circuit-element constants are different from respective ones of said second circuit-element constants, and said first input impedance is the same as said second input impedance.
