GHX-328XSA3B

Antennas RF Overview

The GHX-328XSA3B is a straight whip RF antenna manufactured by Joymax Electronics, designed for sub-1 GHz applications. It operates within two frequency bands: 862MHz to 876MHz and 902MHz to 930MHz, centered at 868MHz and 915MHz respectively. The component features an SMA male plug connector for installation and provides a gain of 2.7dBi in both bands. Key electrical specifications include a maximum VSWR of 1.6 and 1.7, return loss values of -12.7dB and -11.7dB, and a maximum power handling capacity of 1 W. The physical height is limited to 46.00mm.

Antennas RF Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm connector type and impedance matching. Ensure the selected variant aligns with the required frequency band coverage for your target application. Confirm RoHS compliance status if environmental regulations apply to your deployment. Cross-reference the part number with official distributor catalogs to validate current availability and standard lead times before finalizing procurement plans.

Antennas RF Selection Notes

Select this antenna when deploying sub-1 GHz wireless solutions requiring a compact, omnidirectional radiation pattern. The dual-band capability supports global ISM frequencies, making it suitable for regions utilizing either 868MHz or 915MHz allocations. Consider the SMA male connector compatibility with your host device's RF port. The 2.7dBi gain offers a balance between range and size for portable IoT endpoints.
