Crystal RF bandpass filter, heat dissipation area, stable operation and long running time.The filter has a 1dB bandwidth of 4MHz and a steep cutoff.Small size, light weight, low insertion loss, and a center frequency of 868MHz.It has good pass-band ripple coefficient and out-of-band rejection.Performance optimization for 868MHz RFID receivers and European standard LoRa IoT node devices, which can effectively filter out out-of-band signals, reduce noise and increase dynamic rangeImpedance: 50 ohmsCenter frequency: 868MHzPassband (1DB bandwidth): 867~869MHzMaximum Carrying : 100 mW (20 dBm)Interface: SMA-M, SMA-FColour:As shownMaterial:PC+MetalPackage Contents:1 x FilterOnly 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.
