1[FOR 2.4GHz RECEIVER] This filter has low in band insertion loss, with steep cut off characteristics, is dedicated to 2.4GHz receiving device. 2[HIGH EFFICIENCY] The band pass filter can effectively filter out of band signals, reduce noise and increase dynamic range. 3[GOOD SUPPRESSION] Good suppression of out of band remote signals, better than products made with PCB bare boards. 4[SMA INTERFACE] The two ends of the interface are SMAM and SMAF, which is convenient for connection and less loss. 5[LESS INTERFERENCE] Use aluminum alloy shielding shell, has less interference and no out of band spurious response. Item Type: Bandpass Filter Material: Aluminum Alloy Model: FBP-2440s Impedance: 50 Center Frequency: 2440 MHz Pass Band: 2400-2480 MHz Band Interpolation Loss:1 x Bandpass FilterDo not overload to use.
