Murata LFD Series Multilayer Ceramic RF Diplexer

Murata LFD152G45MUAF20 is a chip-type LC diplexer, belonging to the LFD series multilayer ceramic RF filters. It adopts 1005 (0402) package size (1.0×0.5×0.4mm max) with 4-pin surface mount design, specially developed for Wi-Fi 2.4GHz and 5/7GHz frequency bands.

Core Functions

Frequency Band Splitting & CombiningIt separates or combines RF signals of 2.4GHz (2400–2690MHz) and 5.15–7.125GHz (Wi-Fi 6E/7), enabling single-antenna sharing to reduce antenna quantity and save PCB layout space.

Low Insertion Loss & High IsolationInsertion Loss: ≤1.2dB @2.4GHz; ≤1.05dB @5/7GHzIsolation: ≥15dB @2.4GHz; ≥19dB @5/7GHz, effectively suppress mutual interference between different frequency bands.

Miniaturized & Maintenance-FreeIntegrated LC structure with multilayer ceramic technology, ultra-compact 1.0×0.5mm dimension, compatible with reflow soldering, no manual calibration required.

Application Scope

• Wi-Fi 6E/7 Terminals: Smartphones, laptops, tablets, Wi-Fi routers/APs, wireless network cards, supporting 2.4G+5G+7G multi-band coexistence.

• Bluetooth & Wi-Fi Coexistence Devices: Smart speakers, wireless headsets, IoT modules sharing antennas for 2.4GHz Bluetooth and 5/7GHz Wi-Fi signals.

• Industrial & Automotive Communication: Industrial wireless sensors, vehicle-mounted Wi-Fi/Bluetooth modules, intelligent cockpits, compliant with AEC-Q200 automotive-grade reliability standards.

• Medical & Consumer Electronics: Portable medical devices, smart wearables, wireless cameras, ideal for miniaturization and low-power consumption scenarios.
