Adjusting the radio receiver appointed

摘要

The subject innovation is in the first band-pass filter for receiving suppressing unnecessary signal to the RF signal through an antenna, a first band-pass filter for suppressing sinhojung unnecessary signal output from the local oscillator using a X-TAL with the resonator and the first a second band pass through the filter to the mixture receives the signal outputted by mixing to create an intermediate frequency an intermediate frequency to obtain FM demodulation to be particularly, a first band the gain characteristics of the second band-pass filter in accordance with the receiver to receive by providing a wireless receiver configured to adjust appointed characterized in that by matching the gain characteristics of the pass-filter to improve the performance of the reduction in the total of the strong field it can be improved, by using the techniques such as shielding solution.
