1. WLAN Test
1.1.
Purpose
This report is made to check the NM-104BB CX875 module RF performance.
In order to avoid the fail test on RF center frequency error and improve the yield rate of CX875
module, we proposed a solution to fine tune the 50MHz crystal of RF IC by changing the load
capacitors.
This solution was already sending to SMSC review and we also show the performance results in this
report.
