Features: This filter has a 1dB bandwidth of 45MHz and a steep cut-off characteristicThe cut-off characteristic is used to optimize the performance of the 1.4GHz receiver. It can effectively filter out the signal, reduce the noise and increase the dynamic range. FBP~1400 high pass filter signal testing in the 1378~1422 MHz frequency range. Reduces noise, and increases dynamic range. Use aluminum alloy shielded for shell, anti-interference, no out-of-band spurious response, compact and sturdy, easy to use.
