*Crystal RF bandpass filter, large heat dissipation area, stable 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 for RFID receivers and EU for LoRa IoT node devices, which can effectively filter out out-of-band signals, reduce noise and increase for dynamic range Specifications Center Frequency: 868MHz Bandwidth: 867-869MHz Interface Type: SMA Female (external thread, internal hole) + SMA Male (internal thread, internal pin) Dimensions: 35mm x 7mm x 6.5mm Weight: 5.42g Maximum Power Handling: ≤100mW Operating Temperature: -40℃~+85℃ Application Areas 868MHz Wireless Communication Equipment IoT Terminals (e.g., LoRa, Zigbee Modules) RF Signal Processing Systems Test Instruments and Laboratory R&D Precautions for Use: Do not exceed the maximum power handling capacity (100mW) to avoid damaging the device. Avoid mechanical compression or twisting during installation; ensure the interface connection is secure. Store in a dry, non-corrosive environment to extend service life.
