ANT-418-CW-QW-SMA

Antennas RF Overview

The ANT-418-CW-QW-SMA is a single-band RF whip antenna manufactured by TE Connectivity Linx, designed for operation at a center frequency of 418 MHz. It features an SMA male connector for secure interface attachment and utilizes a straight whip form factor. The component operates within a frequency range of 380 MHz to 450 MHz, providing a gain of 2.9 dBi with a voltage standing wave ratio (VSWR) of 1.9. Constructed for panel installation, it includes a 216 mm cable length to facilitate flexible routing during deployment.

Antennas RF Feature Summary

• Utilizes a quarter-wave whip design optimized for efficient radiation patterns in the Sub-GHz ISM band.
• Features an integrated SMA male connector to ensure reliable signal transmission and mechanical stability.
• Incorporates a low VSWR specification to maximize power transfer efficiency between the transmitter and the antenna element.

Antennas RF Applications

• Alarm systems requiring robust wireless communication links
• Industrial, Scientific, and Medical (ISM) radio device implementations
• Remote control applications for automated machinery
• Security system sensor networks

Antennas RF Procurement Notes

Verify that the SMA connector gender matches the receiving port on the target host device. Confirm that the operating frequency aligns with regional regulatory requirements for the 418 MHz band. Ensure the panel mounting method supports the physical dimensions and cable strain relief needs specified in the official datasheet.

Antennas RF Selection Notes

Select this model when a fixed-gain, high-performance whip antenna is required for permanent installations. The SMA interface offers broader compatibility compared to soldered or proprietary connectors. Consider the 216 mm cable length for spatial flexibility in enclosure designs where direct board mounting is not feasible.

Antennas RF Part Context

This component belongs to the CW Series of connectorized antennas from TE Connectivity Linx. The series focuses on Low-Power Wide-Area (LPWA) and LTE applications, offering various form factors including whip and helical types. The ANT-418-CW-QW-SMA specifically addresses the need for standardized connectivity in Sub-GHz deployments.

Antennas RF Replacement Considerations

The ANT-418-PW-QW serves as a functional alternative within the same product family, sharing identical electrical performance metrics such as gain and frequency range. However, it utilizes a different cable configuration and mounting style, requiring evaluation of mechanical fit before substitution.
