2442MHz 2.4GHz SAW Bandpass Filter – Optimized for WLAN & Bluetooth Coexistence

Product Overview:

This model 2442MHz SAW Filter is a high-performance, low-loss RF bandpass filter designed for the 2.4 GHz ISM band. It is specifically engineered to enable seamless coexistence between Bluetooth/WLAN and cellular networks, providing high rejection for LTE Band 7 and Band 40 frequencies.

With a compact SMD footprint and 50Ω unbalanced-to-unbalanced operation, this filter ensures superior signal integrity for smartphones, IoT modules, and wireless networking hardware.

Key Features:

• Center Frequency: 2442 MHz (optimally covers 2403–2481 MHz).

• LTE Coexistence: Exceptional attenuation for LTE Band 7 and Band 40 to prevent cross-interference.

• Low Insertion Loss: Typical 1.8dB loss within the passband for maximum signal range.

• Wide Passband: 78MHz usable bandwidth to support all 2.4GHz WiFi/BT channels.

• Industrial Reliability: Operates from -30°C to +85°C with high ESD protection (HBM 175V).

• Easy Integration: Standard 50Ω input/output impedance (requires 8.2nH shunt inductor for matching).

Typical Applications:

• Wireless Connectivity: Bluetooth Low Energy (BLE), Classic BT, and WLAN (IEEE 802.11 b/g/n).

• Cellular IoT: Wearables and tracking devices with co-located LTE and WiFi radios.

• Smart Home: Zigbee, Thread, and Matter-enabled smart home hubs.
