This filter has a 1dB bandwidth of 26MHz and a steep cutoff characteristic. It is used for performance optimization of 915MHz RFID receivers, effectively filtering out out-of-band signals, reducing noise, and increasing dynamic range. Model: FBP-915s Impedance: 500hms Center Frequency: 915MHz 1dB Passband: 902-928MHz In-band Insertion Loss: less than equal 2.0dB Maximum Power Handling: 100mW (20dBm) Interface: SMA-M, SMA-F This filter has a 1dB bandwidth of 4MHz² and a steep cutoff characteristic. It is used for performance optimization of 868MHz remote controls and rFidt receivers, effectively filtering out out-of-band signals, reducing noise, and increasing dynamic range. Model: FBP-868s Impedance: 500hms Center Frequency: 868MHz Bandwidth (1dB): 866-870MHz In-band Insertion Loss: Less than 3.5dB Maximum Power Handling: 100mW (20dBm) Interface: SMA-M, SMA-F (The product printed words depending on the batch, but this does not affect use) Color:As Shown Material:Metal Package Contents: 1 * Band Pass Filter kits 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.
