AD converter is calibrated in production. AD converter is calibrated in production. Battery Voltage Measurement A D Channel (VBATADC) The battery voltage is scaled inside the UEM in order to avoid external components. The maximum battery voltage that gives a full A D reading is 5.25V. Battery voltage can be connected to sample and hold circuit either through a resistive voltage divider or through a voltage scaling circuit. The voltage scaling circuit is used to get larger input voltage range...

Not used in NHM-8, must be kept disabled Sleep mode is entered when both MCU and DSP are in stand-by mode. Sleep is controlled by both processors. When SLEEPX low signal is detected UEM enters SLEEP mode. VCORE, VIO and VFLASH1 regulators are put into low quiescent current mode. All RF regulators, except VR2, are disabled in SLEEP. When SLEEPX 1 is detected UEM enters ACTIVE mode and all functions are activated. The sleep mode is exited either by the expiration of a sleep clock counter in the...

Transceiver Nhmnx Rf Module

This section describes the RF module for the NHM-8NX transceiver. The RF module includes the RF chip, VCO, PA and surrounding components. NHM-8NX is a dualband E-GSM900 GSM1800 phone, with GPRS (Class 4). The RF engine is based on a RF chip called Mjoelner which contains all the RF functionality including LNA's and reference oscillator. The engine is build for single-sided component mounting. The shielding of the engine is made through two cans with removable lids. One shielding can is for the...

Phone does not register onto the network or the phone cannot make a call

If the phone doesn't register to the network, the fault can be in either BB or RF. Only few signals can be tested since several signals is 'burried' in one or more of the inner layers of the PWB. First of all check that SIM LOCK is not causing the error by using a Test-SIM card and connect the phone to a tester. SIM related faults Insert SIM card fault The hardware of the SIM interface from UEM D200 to the SIM connector X387 can be tested without a SIM card. When the power is switched on the...
