This filter 1DB bandwidth is 4MHz, and the cutoff characteristics are steep. The performance optimization of the 868MHz RFID receiver, the performance optimization of the European LORA Internet Node device can effectively filter out the band signal, reduce noise, and increase the dynamic range. Type: LC Filter Model: FBP-868S Impedance: 50 ohms Center frequency: 868 MHz Tong frequency band (1DB bandwidth): 866~870 MHz With interpolation: Less than3.5 dB Maximum load power: 100 mW (20 dBm) Interface: SMA-M, SMA-F Audio map (labeled 3DB bandwidth in the figure, scan center frequency: 868MHz, blue wire width: 100MHz, vertical scale: 10dB per grid) (For neutral models, remove the label from the product) Material: Metal colour: Silver + gold Package Contents: 2 x SAW Bandpass Filter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
