I found an application note by Googling and made a board based on the reference schematic in the application note.
The board was nicely manufactured but when I tried to measure magnetic field I got some problems: The sensor outputs are too low. An amplifier, MAX4334, is used to amplify the magnetic sensor outputs with about 200 times gain and it seams to work correclty. After server hours of terrible hardware debugging, I eventually found that the Set/Reset strap required by HMC1053 does not work.

Do you still have this app note, the link no longer provide this. I would be grateful if you may send by email riscy00@gmail.com, with much appreciation.
