Checking antenna functionality
Antenna overview
The phone has a main GSM+WCDMA antenna and a BT antenna.
The main antenna assembly consists of an antenna frame with a pattern plated onto the plastic. There is one
feed and one GND contact on the antenna frame.
The BT antenna assembly consists of a BT frame and a BT flex.
Main antenna functionality
The main GSM+WCDMA antenna is functioning normally when the feed and GND contacts take proper contact
to the PWB's C-clips and the plated pattern is visually intact on the antenna frame.
The main antenna functionality must also be checked by measuring the transmitted power with RF coupler
at WCDMA2100 channel 9888.
BT antenna functionality
The BT antenna is functioning normally when the BT antenna contact take proper contact to the PWB's C-
clip, the BT flex is intact and the BT antenna assembly is firmly mounted into the C-cover.
