I would like to upgrade my wireless adapter to a duel band 5ghz. Has anyone performed this yet? If so what manufacturer and part number was used? My current adapter is a Broadcom 504593-003.

Welcome to the HP Support Community!
I reviewed your post and I understand that you want to upgrade the wireless card on your computer.
Don’t worry, I assure you I will try my best to get this sorted.
I checked the specifications of your computer and see that HP has not tested any dual-band wireless cards on your computer. However, you can go ahead and install any dual-band wireless card on the computer and should work fine without any issues. However, I suggest you make sure that the form factor (Size) of the wireless card is exactly the same as the one on the computer.
Alternately, you can use a USB wireless adapter (Dual-band) and plug it to the USB port on the computer.
I hope that answers your question and you have a great day!
