Hi,

my girlfriend has ZTE USB UMTS pen, branded with an operator brand from my country (Portugal) and the model of this pen is MF632, I've searched a lot in Google but I had no success obtaining the connector information and I need this information, obviously to add an external UMTS antenna (she is working at a incredibly low coverage area... on the country...).

My guesses where that it is an CRC9 connector, but I would like your opinions before I spend money on an adapter.


Cheers.
 
Ohhh its a pen-drive sized modem! I googled it and didn't see any 'pens' (I'm slow...). Ok, well, for 3G, the frequency is roughly 2.1Ghz. I'm guessing because its rather a 'big' standard, they may have used a custom connector for the antenna. Many highly miniaturized >1GHz solutions use U.FL SMT connectors.

HRS (HIROSE)|U.FL-R-SMT(01)|RECEPTACLE, SMT, U.FL | Farnell United Kingdom

These are found in bluetooth, and Wlan cards, and I've used em for a couple of projects, simply because I have a few on some scrap laptop WLAN cards, and the cable assemblies/adapters are cheap.

Without a picture, I can only speculate.
 
Thank you for your answer!

Well, thats not the one... I will try to ask her a photo... I will post the photo here ASAP.

This CRC9 male look like it would connect on the one on the USB pen:

But I don't know if that is the one...

The USB connector looks a lot like this one (could be the one... I don't know...) on the Huawei pen:
