Antennas RF Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and variant selection. Confirm that the requested part matches the exact electrical specifications required for the target application, particularly regarding the 2.4GHz frequency band and impedance matching requirements. Cross-reference the manufacturer product number with official Taoglas documentation to avoid substitution errors.

Antennas RF Selection Notes

Select this component for designs requiring a low-profile, high-reliability ceramic antenna suitable for space-constrained portable electronics. Ensure the host PCB layout accommodates the specified ground plane requirements typical for patch antennas. Consider the 2dBi gain and VSWR characteristics when calculating link budget margins for the intended wireless communication range.
