APPLICANT: FCC ID NO: ERICSSON INCAXATR-392-A2 ©1999 Ericsson Inc. EXHIBIT 12A CIRCUIT & DEVICE DESCRIPTIONS PARA. 2.983 (d)(10-12) (10)FREQUENCY STABILIZATION A temperature compensated crystal oscillator (N1302) provides a reference frequency signal for the transmitter and receiver frequency synthesizers. It has an temperature of ±2.5 ppm over the temperature range of -20°C to +50° C. After the unit acquires a base station signal it locks itself to the high accuracy time base of the base station. (11a)ATTENUATION OF SPURIOUS EMISSIONS The 800 MHz band transmitter frequency is obtained from mixing a phase locked VCO operating from 979.53 MHz to 1004.49 MHz with a 155.52 MHz signal. The 155.52 MHz signal is obtained by phase locking an oscillator to the VCTCXO output. The 800 MHz band receiver frequency is obtained by dual conversion. The first conversion is obtained by mixing the incoming signal with the 979.53 MHz to 1004.49 MHz VCO to a first IF frequency of 110.52 MHz. The second conversion mixes the IF frequency with a phase locked VCO at 109.92 MHz to obtain the second IF frequency of 600 kHz. All VCO’s are phase locked to the reference VCTCXO U1. For 1900 MHz band transmit: 1002.765 to 1032.735 MHz synthesizer mixed with a 155.52 MHz signal. Result is then mixed back with the 1002.765 to 1032.735 MHz VCO signal to produce 1850.01 to 1909.95 transmit signal. 1900 MHz band Receive: Output of 1020.285 to 1050.255 MHz synthesizer is doubled to 2040.57 t0 2100.51 MHz. This is used to mix down to a first IF of 110.52 MHz. As a result of the above circuitry, the spurious signals are transmitter harmonics, reference oscillator 19.44 MHz harmonics, the local oscillators and the microprocessor clock. The use of multi-layer printed circuit boards, with signal tracks between ground planes, for the radio as well as for the logic areas reduces the radiation to a minimum. Ceramic resonator bandpass filters for the duplexer attenuate conducted transmitter harmonics, reference oscillator and local oscillator signals. A bandpass filter in the receiver front end attenuates the local oscillator signal further. Additional suppression of radiation is achieved by shielding and key isolation between circuits. (11b)LIMITING MODULATION The modulation for the transmitter is produced inside a Digital Signal Processing integrated circuit. The modulation limiting is therefore controlled by an algorithm inside this chip. The limit is preset at the factory and cannot be changed thereafter. ATTENUATING HIGHER AUDIO FREQUENCIES The DSP chip provides an audio filter with a 120 log (f/3000) response, f=3K to 20KHz. Manchester encoded data signals are filtered prior to transmission by a four-pole lowpass filter providing an attenuation of 24 dB/Octave above 20 kHz. APPLICANT: FCC ID NO: ERICSSON INCAXATR-392-A2 ©1999 Ericsson Inc. EXHIBIT 12A CIRCUIT & DEVICE DESCRIPTIONS PARA. 2.983 (d) (10-12) The signal produced by the DSP chip is a differentially shifted PI/4 QPSK signal for the digital system and a FM signal for the analog cellular system. These signals are fed through a three-pole lowpass filter with a 3 dB down cut-off frequency of 25 kHz to limit the adjacent channel energy in the digital mode. (11c)OUTPUT POWER CONTROL A loop circuit under supervision of the logic sets the output to any of the eleven power levels. A digital word is transmitted to the gain control amplifier for output power adjustment. A detector at the output of the power amplifier module senses the RF energy present and sends a corresponding DC voltage to the digital logic circuitry. Upon receiving a command to set power level from the handset or from a base station the microprocessor sends a predetermined word to the ALC amplifier. The output detector voltage is then read by the microprocessor and compared to a preset value. If the detector voltage is outside the allowed tolerance an adjustment is made to the gain-controlled amplifier to bring the detector voltage into the proper range. (12)DIGITAL MODULATION TECHNIQUES 800 MHz: The NRZ data stream is transformed to 10kbps Manchester encoded data in such a way that each NRZ binary one is transformed to a zero-to-one transition, and each NRZ binary zero is transformed to a one-to-zero transition. The Manchester encoded data stream is filtered before being applied to t he modulator. Direct binary frequency shift keying is used. A binary one into the modulator corresponds to a normal peak frequency deviation of 8kHz above the carrier frequency and a zero corresponds to a nominal peak frequency deviation 8 kHz below the carrier frequency. (12a)DESCRIPTION OF PI/4 DQPSK The modulation method used for the digital mode is known as PI/4 shifted differentially encoded Quadrature Phase Shift Keying. Eight distinct phase states are possible. The signal information is differentially encoded; symbols are transmitted as changes in phase rather than absolute phases. Transition of phase which would result in zero amplitude momentarily are not allowed. APPLICANT: FCC ID NO: ERICSSON INCAXATR-392-A2 ©1999 Ericsson Inc. EXHIBIT 12A CIRCUIT & DEVICE DESCRIPTIONS PARA. 1.0 LOGIC BOARD OPERATION The logic board is the central controller system for the radio. It is made up of a microprocessor, DSP, codec, memory, and control logic. 1.1 ASIC CONTROL CHIP – D1001 The ASIC control chip is made up of an ARM microprocessor and application specific logic circuits. The chip is the main control center for the radio and provides interfaces to the DSP, codec, memories, keypad, display, alarms, and system interfaces. 1.2 MEMORY CHIP’S D901 is the 1M x 8 flash memory used to store the radio’s operating algorithm.

Introduction In this test report, Specific Absorption Rate (SAR) measurements for the Ericsson T18D portable telephone are presented. The measurements were conducted at the dosimetry laboratory at Ericsson, Inc. in Research Triangle Park, North Carolina, USA. The report describes the test procedures that were used and the test results that were recorded. 2.

Measurement System The measurements were made with the Dosimetric Assessment System, DASY, from Schmid & Partner AG (SPEAG) in Zurich, Switzerland. This system was developed by Professor Niels Kuster and his team at the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland [II]. The system uses the implantable E-field probe technique to evaluate the SAR inside the generic twin phantom. The E-field is automatically scanned inside the phantom filled with a brain tissue simulating liquid [III]. The positioning of the E-field probe inside the left phantom head is done by a high-precision 6 axis robot. A computer is used to control the robot and to collect the measured data. 3.1 Specification for the E-Field probe The following is a summary of the technical data for the E-field probe that is used for the measurements. • Sensitivity in tissue simulating liquid:1 μW/g to 100 mW/g • Linearity:< ± 0.2 dB • Deviation from isotropy in tissue, • Normal to probe axis:± 0.2 dB • In all planes, all polarizations:± 0.8 dB Confidential REPORT 3(11) Prepared (also subject responsible if other)No. RT/EUS/TR/X Mark Douglas919-472-6334 EUS/TR/X-99:1222 ApprovedCheckedDateRevFile EUS/TR/X Mark DouglasMGD1999-02-16A U:\FCC_TRNS\Fcc_392\Exhibit 11\exhbt_11SAR.doc EN • Spatial resolution of SAR measurements:< 0.125 cm 3 • Reproducibility of probe positioning:< ± 0.2 mm A more detailed description of the system is given in references [I] and [II]. 3.2 Brain tissue simulating liquid data The electrical data used for the brain tissue simulating liquid are according to the data provided by C. Gabriel. The liquid is prepared using the recipe [V] for the brain tissue simulating liquid. The electrical parameters of the brain tissue simulating liquid are measured at room temperature by the HP 85070B dielectric probe kit from Hewlett Packard. This probe kit uses an open-ended coaxial probe and a network analyser to measure the electrical data for the liquid. The following values were measured for the relative permittivity (εε r ) and conductivity (σσ) for the liquids that were used during the SAR measurements. f ( MHz ) 8351800 εε r 44.340.1 σσ ( S/m ) 0.771.67 3.3 Calibration The system is calibrated at fixed time intervals by the supplier of the system (SPEAG). The E-field probes are calibrated every 12 months by the supplier. A detailed description of probe calibration is found in reference [IV]. 3.4 Validation Immediately before measuring the SAR of the device under test, the measurement system was validated by measuring the SAR of a standard dipole antenna located a set distance underneath a flat phantom. The measured results are compared with expected values that are recorded in reference documents. The results are given below. 1 gram averaged SAR (W/kg) DipoleOutput Power (W) ExpectedMeasured difference (%) D900V219.248.893.8 D1800V2112.512.82.4 3.5 Measurement Tolerance The total measurement uncertainty is estimated to be ±25% [II]. 4. Test Procedure The dosimetric assessment measurements are made according to the operating manual for the DASY3 system from SPEAG. A base station simulator was used to control the phone during the SAR measurements. The phone was supplied with a fully-charged battery for the tests. The SAR is measured at three frequencies (corresponding to the low, middle and high frequencies of the band). 4.1 Positioning of the Device Under Test Confidential REPORT 4(11) Prepared (also subject responsible if other)No. RT/EUS/TR/X Mark Douglas919-472-6334 EUS/TR/X-99:1222 ApprovedCheckedDateRevFile EUS/TR/X Mark DouglasMGD1999-02-16A U:\FCC_TRNS\Fcc_392\Exhibit 11\exhbt_11SAR.doc EN The D.U.T. is placed in a position against the phantom head that corresponds to the intended or normal operating position.

Mr. Chan and I have discussed and resolved the open issue. Attached are the correspondence between Mr. Chan and I for you reference. I hope this memo resolves any questions you may still have and we can receive a grant for this filing by May 7, 1999. If you have any questions regarding this filing, please feel free to contact me. Jim Sponsler [email protected] 919-472-6460 Jim: Attached is a copy of the comments on AXATR392-A2, which was sent to Errol on 04/16/99. Kwok Chan EAS 93434, Ericsson [ The above file EAS93434... is printed out below for your reference] Errol: This is the Ericsson dual band, dual mode phone, EAS 93434, AXATR392-A2 - 1.They are requesting 400 mW ERP for AMPS and TDMA modes in the cellular band and 400 mW EIRP in the PCS/TDMA mode as shown on 731 form. Measured ERP for AMPS mode is 214 mW and EIRP for PCS/TDMA mode is 375 mW. Conducted outputs of around 25.48 dBm (347 mW) for the AMPS mode and 26.47 dBm (443 mW) have been indicated in different plots for other test procedures. SAR was measured at conducted output levels of around 25.6 dBm for AMPS mode, 25.5 dBm for cellular TDMA and 24.8 dBm for PCS/TDMA. These differences need to be clarified for determining the proper output ratings for the grant and the maximum ratings should not exceed those tested for SAR. 2.The alignment procedures call for +26 dBm at power steps 0-2 with +/- 0.25 dB at mid-channel and +1/-1.5 dB at high and low channels. The highest SAR is 1.4 W/kg (AMPS mode) which occurs at the low frequency (824 MHz). The tolerance in the alignment procedures can cause SAR to exceed the 1.6 W/kg limit. Please clarify and also indicate if the alignment procedures apply to specific operating modes or all modes. 3.The clarification for 1 & 2 above will be used to determine the output ratings to be listed on the grant, which represent the maximum ratings for all production units and must satisfy RF exposure limit. Kwok Chan To: Kwok ChanFrom: Jim Sponsler Date: 4-26-99 Confirmation Number: EA93434 Filing: AXATR-392-A2 This memo is in response to your email concerning the AXATR-392-A2 ( EA93434) power measurements and SAR. I recommend we change our declared power on the 731 form to: 23.3 ERP typical output power for 800 band and declare 25.7dB for the 1900 band. These values represent those in the below table. The alignment procedure needs to be revised. I will change the procedure to reflect the values shown above upon your agreement with them. The differences between the power measurements are shown below. I believe the results are within the measurement error of testing at different locations and/or using different equipment. As shown below, the test equipment type also changed and this is due to what is available at the different locations or labs. All results are in dBm and conducted unless noted otherwise.
