Hi Martin,

The A5645H is the latest version of the A5645 antenna. Some gigaNOVA antennas, including Mica, have been refreshed recently, so they're now using halogen-free materials. These have a lower environmental impact! There are no notable performance differences between the two, according to the data sheets.

We'd suggest using Mica A5645H for all new designs for the reasons outlined above.

Hopefully that answers your question.

Hi Matt,

on the datasheet of the A5645H I cant find any specifications regarding eg. gain. All this seems to be missing compared to the A5645. Can you please let me know if there is any difference in this regard? My other question is if the A5645H is suitable as a direct swap. Our PCB was designed for the A5645.

Can you also shed some light on if you’d expect it to affect the matching components significantly (is it a full drop-in replacement)?
