The filter has a 1dB bandwidth of 4MHz and a steep cut-off characteristic. The performance optimization of 868MHz remote controller and RFID receiver can effectively filter out out-of-band signals, reduce noise and increase dynamic range.Model: FBP-868sImpedance: 50 OhmsCentral frequency: 868 MHzPassband (1dB bandwidth): 866-870 MHzInterpolation loss: < 3.5 dBMaximum load power : 100 mW (20 dBm)Interface: SMA-M, SMA-FFrequency response diagram (marked as 3dB bandwidth):
