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