Features 1、Center Frequency: This filter provides center frequency with low insertion loss and steep cutoff characteristics. 2、Noise Reducing: The bandpass filter effectively filters out of band signals to reduce noise, increase dynamic range and improve stability. 3、Internal PCB: The bandpass filter has a thin PCB board inside, which still has excellent suppression capability and good performance for out of band far end signals. 4、Aluminum Alloy Shielding Housing: The bandpass filter uses aluminum alloy shielding housing, which is interference resistant and has no out of band spurious response. 5、Application Scenarios: Our bandpass filter is dedicated to the performance optimization of RC (model airplane, drone aerial photography) receiver devices.
