Contents FCC - SAR European Union - SAR SAR (FCC) This Model phone meets the FCC Requirements for exposure to radio waves. Your Mobile Phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the limits for exposure to radio frequency (RF) energy recommended by the Council of the European Union. These limits are part of comprehensive guidelines and established permitted levels of RF energy for the general public. The guidelines were developed by independent scientific organizations through the evaluation of scientific studies. The limits include a substantial safety margin designed to ensure the safety of all persons, regardless of age and health. The exposure standards for mobile phones employ a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit recommended by FCC is 1.6 W/kg.* Tests for SAR have been conducted using normal operating conditions with the phone transmitting at the highest certified power in all tested frequency bands. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to the station antenna, the lower the power output. Before a phone model is available for sale to the public, compliance with FCC must be shown. One of the essential requirements of this directive is the protection of the health and safety for the user and any other person. The highest SAR value for this model phone when tested for compliance against the standard is 0.713 W/kg. While there may be differences between the SAR levels of various phones and at various positions, they all meet the FCC requirement for RF exposure. The SAR limit for mobile phones for public use is 1.6 watts/kilogram (W/kg) averaged over ten grams of body tissue. The limit incorporates a substantial margin of safety to give additional protection for the public and to account for any variations in measurements.

They include the following. a) DB2068C User’s Manual b) DB2068C Transceiver Data Sheet c) GSM System Specification. d) DB2068C Radio Circuitry Description The DB2068C User’s Manual provides the necessary information to operate a mobile. DB2068C Traceiver Data Sheet provides some information for the RF part. The DB2068C Radio Circuitry Description .Circuitry Description provides information on the circuits relevant to FCC certification. 4.0 O verview The attached picture is DB2068C BLOCK diagram. 4.1DB2068C Radio Module Circuit Architecture The circuit can be powered-up into four different modes, RX, TX, SYN or REF mode, depending on supply voltages applied, the logical level at pins RXON/TXON/SYNON and the 3-wire bus serial programming. In RX (TX) mode, all sections required for receive (transmit) are turned on. The SYN mode is used to power-up the synthesiser and the RF VCO prior to the RX or TX mode. In the SYN mode, some internal LO buffers are also powered-up such that VCO pulling is minimized when switching on the receiver 4 or the transmitter. The reference oscillator (REF mode) is turned on by applying the supply voltage. Additionally band selection is done using the 3-wire bus serial programming allowing the proper enabling of the LNAs and TX charge-pump current programming. 5.0 FUNCTIONAL DESCRIPTION RF Receiver The receiver front-end converts the aerial RF signal from GSM850 (869-894 MHz), GSM900 (925 - 960 MHz), DCS(1805 - 1880 MHz) or PCS (1930 - 1990 MHz) bands down to a low intermediate frequency (IF) of 100 kHz. The first stages are symmetrical low noise amplifiers (LNAs). They are matched to 50 W using external baluns. The DCS inpurs can also be used for PCS operation. The LNAs are followed by an I, Qdown-mixer. It consists of two mixers in parallel but driven by quadrature out of phase LO signals. The In phase (I) and Quadrature phase (Q) IF signals are low pass filtered to provide protection from high frequency offset interferers. The low IF I and Q signals are then fed into the channel filter. Channel filter and AGC The front-end low IF I and Q outputs enter the integrated bandpass channel filter with provision for five 8 dB gain steps in front of the filter. The filter is a self-calibrated fifth order band-pass filter centred around 100 kHz and has a bandwidth of 240 kHz for GSM 5 mode, 300kHz for EDGE mode. Being filtered the low IF I and Q are further amplified with provision for ten 4 dB gain steps and fully integrated DC offset compensation. Realised with an active high pass circuit this compensation either operates continuously or keeps the acquired offset correction during the bursts depending on the programming. The low IF output buffer provides close to rail-to-rail output signals. IQ modulator I and Q baseband signals are applied to the IQ modulator that shifts the modulation spectrum up to the transmit IF. It is designed for low harmonic distortion, low carrier leakage and high image rejection to keep the phase error as small as possible. The modulator is loaded at its IF output by an integrated low pass filter that supress unwanted spurs prior to get into the phase detector. The clock drive is generated by division of the RFLO signal provided for the transmit offset mixer. Transmit modulation loop The analog transmit modulation loop is composed by an on-chip offset mixer with spur filter and by a phase/frequency detector with charge pump. The loop is closed off-chip by a loop filter and transmit VCO. The analog PLL copies the modulation to the off-chip transmit VCO and acts as a tracking filter. A PLL of at least third order is required to meet noise requirements at 20 MHz offset from carrier. The PLL bandwidth must be greater than 700 kHz in order to keep a low dynamic phase error and to minimize the acquisition time. The IF frequencies used are about 60 MHz. RF VCO The RF VCO is fully integrated and self calibrating on manufacturing tolerances. It consists of 64 different frequency ranges that are selected internally depending on the frequency programming. It covers the necessary bandwidth of 3476 to 3980MHz and is tuned via the RF charge pump and the external loop filter. An internal supply voltage regulator using VCC(RFLO) as input supplies the RF VCO and minimises parasitic couplings and pushing. This regulator and the RF VCO are turned on by the SYNON signal. The 64 different frequency ranges are realised by switching of varactors’ cathodes between GND and the regulated RFVCO supply. RF LO section The RF LO section covering the 3476 to 3980 MHz bandwidth is driven by the internal RF VCO module. It includes the LO buffering for the RF PLL, a divider by two or one for GSM850/GSM900 and DCS/PCS respectively which drives a quadrature generation network to supply the RX IQ down-mixer or it drives the transmit modulation loop offset mixer and the clock divider driving the IQ modulator.Philips Semiconductors Objective specification Low power GSM850/GSM900/DCS/PCS multi-band transceiver UAA3536HN/C2

They include the following. a) DB2068C User’s Manual b) DB2068C Transceiver Data Sheet c) GSM System Specification. d) DB2068C Radio Circuitry Description The DB2068C User’s Manual provides the necessary information to operate a mobile. DB2068C Traceiver Data Sheet provides some information for the RF part. The DB2068C Radio Circuitry Description .Circuitry Description provides information on the circuits relevant to FCC certification. 4.0 O verview The attached picture is DB2068C BLOCK diagram. 5 5.1 Test Equipment Requirements The following test equipment(or equivalents) are required to properly tune the DB2068C Radio module. 1. Tested radio module needs a RF connection. 2. Personal computer(Host station) with the RF TEST test software(TAT) 3. R&S DC power supply. 4. R&S spectrum analyzer. 5. Radio tester(R&S CMU200) 6.GPIB-Bus and serial link. 6 5.2 Introduction This section describes the steps to take before the actual alignment of the radio should begin. The effort in this section is to visually inspect the assembled radio part with test equipment(CMU200). Visually inspect the radio to verify all components have been installed. 5.3 Tuning Procedure This section describes the procedure required and procedure to manually align the transmitter and receiver circuitry. 5.3.1 AFC(Auto frequency control): The TXVCO is used to drive the quadrate modulator circuit. It is necessary to tune the TCXO to align the 26MHz so that it will oscillate at with the proper tuning voltage TCXO PIN 1.Set-up the radio-tester in the GSM900, non-signaling TX-mode (e.g. channel 62).Set the transmission-mode to burst, the bit modulation on with no training sequence let the phone start random TX-bursts on channel 62 with the power level 10 (the other default values have to be present on the RAM!) It is assumed that the relation between ∆f and the DAC-value is a linear equation. So it is enough to determine two points of that curve to know the whole relation. The first point you get when you set the DAC to a certain value (for example 1000) and measure the resulting frequency error with the radio tester. The second point you get in the same way, but with another DAC setting (for example 3000) 7 5.3.2 APC Transmit part: The task of this part is to calibrate GSM peak power and the curve of time mask(power ramping curve). Average power is the most important parameter in the TX part. Accurate timing of burst prevents the interference between adjacent slots. The stored parameters in the EEPROM include Ham0, PowH0 and Ham15, TRU and TRD and so on. 8 Align at least 20 boards manually (with the exact RF peak-power levels respectively, according to GSM-specification) and notice the achieved values for every board. Get the corresponding power of the Ham0-DAC-values (PowH0), first set the Ham15 (peak-power)-value equal to the Ham0-value and then measure the new power with the radio tester. Average the various obtained DAC-levels to the default DAC-levels (Ham0, PowH0 and Ham15, TRU and TRD). Now we have all values we need for alignment:-the default values for TRUand TRD-the (default) pairs of values of Ham0/PowH0and Ham15/PowPeak(PowPeakare the various peak-power levels according to GSM-spec.) 5.3.3AGC (Auto gain calibration):This part will calibrate RX parameter that stored in EEPROM to satisfy with received different signal strength. The stored parameters in the EEPROM include a_rf_FineGain and so on. Set-up the Radio Tester (CMU) to generate RF-bursts(-> GPIB interface or by hand).Cable attenuation has to be compensated for the different frequency-bands. Set frequency to channel 62 (channel 698 for DCS). Set power level to -60 dBm. Set bit modulation to PRBS, transmission to continuous. Read out the power reported by the phone. Calculate the difference between the measured power and the expected power (-60 dBm)(= DiffPower). Store the new value of a_rf_FineGain = ( a_rf_FineGaindef-DiffPower )x 8to the RAM. Remeasure the reported power, ensure that the difference should less than 0.1Db. Set the radio tester to another frequency. Repeat the steps above for further frequencies (in our case: 5 frequencies). 9 6.0 Tune-up Target PCL = 0, PWR = 29.4 ± 0.2 dBm PCL =1, PWR = 28 ± 0.2 dBm PCL =2, PWR = 26 ± 0.2 dBm PCL =3, PWR = 24 ± 0.2 dBm PCL =4, PWR = 22 ± 0.2 dBm PCL =5, PWR = 20 ± 0.2 dBm PCL =6, PWR = 18 ± 0.2 dBm PCL =7, PWR = 16 ± 0.2 dBm PCL =8, PWR = 14 ± 0.2 dBm PCL =9, PWR = 12 ± 0.2 dBm PCL =10, PWR = 10 ± 0.2 dBm …
