Model Number: Filter - This bandpass filter is specifically designed with a model number 'Filter', tailored for high and reliability in RFID receivers operating at 868MHz, ensuring optimal performance in EU IoT applications. : Electrical - Perfect for electrical DIY enthusiasts and professionals, this bandpass filter facilitates seamless integration into custom projects and IoT devices, enhancing signal clarity and reducing interference. Two sides are gold-plated SMA connectors (one side is SMA female head - external threaded inner hole; On the other side is the SMA male head with internal thread, designed as a double-sided circuit board with high mechanical strength and stable electrical performance. Small size, light weight, low insertion loss, center frequency of 868M Description/Features: Experience enhanced signal clarity with our Crystal Bandpass Filter, designed specifically for 868MHz RFID receivers and EU LoRa IoT node devices. This compact and filter boasts a large heat dissipation area, ensuring stable performance over extended operating periods. With a 1dB bandwidth of 4MHz and a steep cutoff, it effectively filters out-of-band signals, reduces noise, and increases the dynamic range. The filter also features low insertion loss and excellent pass-band ripple coefficient and out-of-band rejection, optimizing your device's performance in demanding environments. Specifications: Impedance: 50 ohms Center Frequency: 868MHz Passband (1dB Bandwidth): 867~869MHz In-band Insertion Loss: < 2 dB Maximum Carrying Power: 100 mW (20 dBm) Interface: SMA-M, SMA-F Color: As Shown Material: Metal Package Contents: 1*868MHz RFID 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.
