2.4GHz BandPass Filters 2400-2450 MHz WiFi BlueTooth ZigBee

Bandpass Filters for 2400 & 2450 MHz Frequency Bands

Product Overview

We offer bandpass filters designed for the 2400–2450 MHz frequency range, optimized for high-performance wireless communication.

• 2400 MHz Version
• Internal version (no case): SMA-female connectors on both ends.
• 2450 MHz Version
• Standard: SMA-female connectors on both ends.
• Customization
• RP-SMA connectors available upon request for large orders.

These filters are suitable for Bluetooth, Wi-Fi (2.4 GHz), ZigBee, and all other ISM-band applications.

Key Functionality

A bandpass filter allows signals within the designated 2400–2450 MHz band to pass through while attenuating or rejecting frequencies outside this range. This reduces interference and improves overall system performance.

Primary Benefits:

• Interference Mitigation – Rejects unwanted signals in the crowded 2.4 GHz band.
• Improved Receiver Sensitivity – Enhances range and reliability by passing only the desired frequencies.
• Regulatory Compliance – Helps meet FCC and international standards by minimizing out-of-band emissions.
• Frequency Planning Support – Assists in channel isolation for large-scale IoT and wireless deployments.

Applications

Wi-Fi & Bluetooth

• Ensures cleaner connections across multiple 2.4 GHz channels.
• Balances bandwidth and rejection to maintain stable throughput.

ZigBee & IoT Networks

• Improves device-to-device communication in dense deployments.
• Reduces packet loss caused by overlapping signals.

ISM Band (Industrial, Scientific, Medical)

• Protects sensitive equipment from harmful interference.
• Essential in environments with mixed wireless and sensing devices.

Why Bandpass Filters Matter in the 2.4 GHz Spectrum

The 2.4 GHz ISM band is one of the most congested wireless environments, shared by countless devices worldwide. Bandpass filters are critical tools for engineers and system designers to:

• Maintain signal integrity in Wi-Fi, Bluetooth, ZigBee, and IoT applications.
• Support reliable long-range communication.
• Enable efficient spectrum use in large-scale deployments.

As IoT ecosystems continue to grow, the importance of precise filtering solutions cannot be overstated. For developers, integrators, and network engineers, bandpass filters are essential for unlocking the full potential of 2.4 GHz wireless systems.
