L000558-05

Antennas RF Overview

The L000558-05 is a high-density printed circuit board antenna manufactured by TE Connectivity Linx, designed for Low Power Wide Area Network (LPWAN) applications. It operates within the UHF frequency range of 863 MHz to 870 MHz, with a center frequency of 866.5 MHz, targeting ISM band usage. The component features a flat flexible cable (FPC) design with a total length of 100 mm and utilizes an MHF4L connector for termination. Key electrical specifications include a gain of 1 dBi and a Voltage Standing Wave Ratio (VSWR) of 1.5. The antenna supports a maximum power handling capacity of 10 W and is intended for adhesive mounting.

Antennas RF Feature Summary

• Optimized for LPWAN protocols including LoRaWAN in the 868 MHz ISM band
• Compact high-density profile suitable for space-constrained IoT devices
• Integrated 100 mm cable with MHF4L interface for direct RF module connection

Antennas RF Applications

• LoRaWAN sensor nodes
• Industrial IoT telemetry modules
• Smart metering equipment

Antennas RF Procurement Notes

Verify that the MHF4L connector type matches the host device's RF port, as standard MHF4 connectors are not compatible. Confirm adhesive mounting requirements against the target enclosure material to ensure reliable mechanical fixation. Check lead times as manufacturing may involve specific production schedules. Ensure the operating environment does not exceed the specified power handling limits.

Antennas RF Selection Notes

Select this model when a low-profile solution is required for 868 MHz ISM band operations. The 100 mm cable length provides routing flexibility compared to shorter variants. Consider the 1 dBi gain and VSWR performance for link budget calculations. This antenna is suitable for applications where internal placement within plastic enclosures is necessary without external protrusion.

Antennas RF Part Context

This part belongs to the L000558 series of high-density FPC antennas from TE Connectivity Linx. The series offers various cable lengths and connector options tailored for different form factors. The L000558-05 specifically addresses the need for compact integration in portable or embedded wireless devices requiring robust LPWAN connectivity.

Antennas RF Replacement Considerations

The L000558-02 is a variant within the same family featuring a 100 mm cable but may differ in specific impedance or tuning details. Verify cross-compatibility with existing PCB layouts and connector placements before substitution.
