2.4GHz BandPass Filters 2400-2450 MHz WiFi BlueTooth ZigBee

Band pass filters for frequency bands 2400 & 2450 MHz 

• The 2400MHz version has an SMA-male connector and an SMA-female connector on the other end. 
• The 2450MHz version has SMA-female connectors on both ends. 
• If you need RP-SMA connectors for a large order, we can customize the connectors.
• Suitable for Bluetooth, 2400MHz Wi-Fi, ZigBee and all other applications in the 2400 MHz frequency band
• Allows signals wtih the specific 2400 MHz frequency band range to pass through while attenuating or rejecting signals outside this range. Mitigates interference and enhance overall system performance.

Applications & Benefits in Wi-Fi, Bluetooth, ZigBee & ISM

The applications of bandpass filters in WiFi networks, and Bluetooth and ZigBee applications, are diverse and critical to the success of these wireless communication technologies:

1. Interference Mitigation:  The 2400~2450 MHz band is shared by various wireless devices and systems.  Our bandpass filters help reject interference from other signals, ensuring the robustness of BT, ZigBee, ISM and WiFi connections.

   • Wi-Fi and Bluetooth Applications:  Our bandpass filters handle multiple channels within the 2.4 GHz band, with a balance between bandwidth and rejection.
   • Industrial, Scientific, and Medical (ISM) Applications: These filters provide strong rejection of out-of-band signals to avoid interference with critical communication or sensing equipment.

2. Improved Receiver Sensitivity: By selectively passing only the desired frequencies, bandpass filters enhance the receiver's sensitivity, enabling Wi-Fi, Bluetooth, and ISM devices to operate at extended ranges.

3. Frequency Planning: In large-scale 2400~2450 MHz wireless IoT and network deployments, effective frequency planning is essential to avoid network congestion. Bandpass filters aid in isolating specific channels within the 2400 MHz band, facilitating efficient frequency allocation. 

4. Compliance with Regulations:  Regulatory agencies including the Federal Communications Commission (FCC) in the United States, have strict rules governing the use of the 2400-2450 MHz band. Bandpass filters assist in complying with these regulations by limiting emissions outside the designated band.

A bandpass filter designed for 2400~2450 MHz is typically used in radio frequency (RF) and wireless communication systems including IoT applications, Bluetooth, WiFi, and other applications operating in the industrial, scientific, and medical (ISM) band.  As the IoT landscape continues to expand, the importance of these filters in achieving reliable and long-range wireless communication cannot be overstated. Engineers and developers in the field of IoT and wireless communication should consider bandpass filters as essential tools in their arsenal for achieving optimal performance in the 2400 MHz spectrum.
