RM-348; RM-349; RM-350 RF Troubleshooting RF Tunings Introduction to RF tunings Important: Only perform RF tunings if: • one or more of the RF components have been replaced • flash memory chip is replaced or corrupted. RF calibration is always performed with the help of a product-specific module jig, never with an RF coupler. Using an RF coupler in the calibration phase will cause a complete mistuning of the RF part. Important: After RF component replacements, always use autotuning.
RM-348; RM-349; RM-350 RF Troubleshooting Phoenix preparations Install the phone-specific data package. This defines the phone-specific settings. Auto tuning procedure 1 Make sure the phone (in the jig) is connected to the equipment. Else, some menus will not be shown in Phoenix. 2 To go to autotune, select Tuning (Alt-U) > Auto-Tune (Alt-A) from the menu. 3 Remember to set the correct attenuation values before autotuning. 4 To start autotuning, click the Tune button.
RM-348; RM-349; RM-350 RF Troubleshooting PA (power amplifier) detection Context The PA detection procedure detects which PA manufacturer is used for phone PAs. If a PA is changed or if the permanent memory (PMM) data is corrupted, PA detection has to be performed before Tx tunings. Steps 1. From the Operating mode drop-down menu, set mode to Local. 2. Choose Tuning→PA Detection . 3. Click Tune. 4. Check that the detected PA manufacturers are corresponding to the actual chips on the board. 5.
RM-348; RM-349; RM-350 RF Troubleshooting 5. Click Start. 6. Connect the signal generator to the phone, and set frequency and amplitude as instructed in the Rx Calibration with band EGSM900 (step 1-3) pop-up window.

RM-348; RM-349; RM-350 FMTx 2.0 Troubleshooting _RST Also, the _RST signal to the device can be monitored. This is an active low signal and should only be asserted during power up. The _RST signal is driven by the PURX line. The state of pins 19 & 18 (GPO1 and GP02 respectively) on the rising edge of the _RST pin determines what interface is selected when the device powers up.

Using this method it is possible to reduce the effective ppm of the reference clock down to +/- 14ppm over the full operating temperature range of -15 to +50 degrees Centigrade. General visual inspection guidelines • Check that the Si4713 device is placed correctly on the PWB and that there are no obvious signs of damage.

The external interface is the micro-B connector X3300. The interface between D3300 USB transceiver and micro-B receptacle is the standard USB interface specified in the Universal Serial Bus specification Rev. 2.0.
RM-348; RM-349; RM-350 System Module and User Interface Figure 57 SIM interface The EM ASIC handles the detection of the SIM card. The detection method is based in the BSI line. Because of the location of the SIM card, removing the battery causes a quick power down of the SIM IF. The EM ASIC SIM1 interface supports both 1.8 V and 3.0 V SIM cards. The SIM interface voltage is first 1.8 V when the SIM card is inserted, and if the card does not response to the ATR a 3 V interface voltage is used.

RM-348; RM-349; RM-350 System Module and User Interface Signals with different frequencies take different paths, therefore being handled by different components. The principle of GSM and WCDMA is the same. Transmitter (TX) The digital baseband signal (eg. from the microphone) is converted to an analogue signal, which is then amplified and transmitted from the antenna. The frequency of this signal can be tuned to match the bandwith of the system in use (eg. GSM900).
