Features: brand new and high quality The filter has a 1dB bandwidth of about 100MHz and a steep cutoff characteristic For WiMAX signal testing for the 2555 - 2655 MHz frequency range effectively filters out-of-band signals. Reduces noise, and increases dynamic range. It is dedicated to the performance optimization of 2600MHz receiving equipment. Use aluminum alloy shielded for shell, anti-interference, no out-of-band spurious response, compact and sturdy, easy to use.
