PURPOSE: An RF signal processing circuit is provided to efficiently process a filtering of an IF(Intermediate Frequency) signal. CONSTITUTION: A signal processing unit receives an RF(Radio Frequency) signal. The signal processing unit creates an IF signal. The IF(Intermediate Frequency) filter filters the IF signal in a frequency of a predicted band. The IF filter comprises a first BPF(Band Pass Filter) and a second BPF. The second BPF is arranged in parallel with the first BPF. The first and the second BPF filter comprises inductor and a capacitor which is connected with the inductor in parallel. |
