you can use simulator like TINA-TI with say a programmable gain amplifier (ex: PGA849) and try to tune it. even filter frequency you can evaluate there once you decide what is your frequency of interest and choose a type of filter(lowpass, bandpass).
sensor/detector --> pass filter(pick desired freq band) --> more filter stages? --> Amplifier(programmable gain if your reception response is dynamic) --> sampling with ADC
