In the AMQ 7 documentation[1] , it is mentioned that AMQ broker can be downloaded from access.redhat.com and is available in 2 formats:
1) An archive in .zip format (for any supported OS: Linux, Unix, or Windows) or
2) An archive in .tar.gz format (for any supported OS with the tar and gunzip commands, typically *nix)

But only the ZIP file is available for download[2]
