Open EXHIBIT 13 1 (2) Prepared (also subject responsible if other) No. EAB/PJR/IR Per Helmersson B5KDKRC1311005-2 Uen Approved Checked Date Rev Reference KI/EAB/PJR/IR (P Helmersson) 2006-09-07 A Federal Communications Commission Authorization & Evaluation Division 7435 Oakland Mills Road Columbia, Maryland 21046 Attention: Equipment Authorization Branch SP Sveriges Provnings- och ForskningsInstitut Brinellgatan 4 Box 857 S-501 15 Borås Sweden September 7, 2006 Subject: Certification for FCC ID: B5KDKRC1311005-2 Gentlemen; Ericsson AB requests a Grant of Certification (Type Acceptance) for the mentioned FCC Identifier above. This base station transceiver is designed for use in the GSM 800 MHz cellular telephone system. The transmitter will operate from 869.2 to 893.8 MHz. The receiver circuit supports 824.2 to 848.8 MHz. The base station operates in the 800 MHz broadband Cellular services as per 47 CFR Part 22 subpart H. It meets the requirements of GSM1900 11.10-1 version 4.19.1 specification for operation in GSM cellular systems except for the output frequency range. The transceiver can be used in the base station models RBS 2106, RBS 2107, RBS 2206 and RBS 2207. These base stations will in normal mode operate at a nominal power out of 46.3 dBm for GMSK and 43 dBm for 8- PSK at the antenna connector when using combiner unit CDU-G or CDU-J. In TCC mode with two transmitters combined on the same frequency the nominal output power is 49 dBm for GMSK and 45.7 dBm for 8-PSK. The power output is reducible to ~0.3 watts . The transmitter path in CDU-G and CDU-J is identical. Due to the too wide frequency spectrum at the band edges the output power has to be reduced in some cases. In both GMSK and 8-PSK mode the output power in channel 128 – 869.2 MHz and channel251 – 893.8 MHz has to be reduced to a maximum of 38.3 dBm. Ericsson AB requests confidentiality under CFR 0.459. Confidentiality for the following exhibits is requested: Exhibit 4 Block diagram Exhibit 5 Part 1 Schematics Exhibit 5 Part 2 Schematics Exhibit 8 Internal manuals Exhibit 9 Internal photos Exhibit 10 Components, Tune Up The Radio Base Station (RBS) is always installed and placed in an area with access only to authorize personal.

There are 122 Channels available with a channel spacing of 200 KHz. The transmitter is capable of operation in a TDMA (Time Division Multiple Access) system. For each channel there are 8 time slots available, each containing digital speech or data for GMSK and data for 8-PSK. The dTRU have a hybrid combiner included which can be used to increase the number of TRX:s per antenna. The combiner can alternatively be used to increase the output power (TCC = Transmitter Coherent Combining) by using the same transmit frequency channel in both TRX:s. This combiner is connected before the cavity band pass filter in the combining system. 1.2 (4) Type of Emission: GMSK: 244KGXW 8-PSK: 244KG7W 1.3 (5) Frequency range. 869.2 to 893.8 MHz 1.4 (6) Range of Operating Power: This transmitter is designed to supply a nominal power level of 46.3 dBm for GMSK and 43.0 dBm for 8-PSK at the antenna connector using combiner unit CDU-G or CDU-J. The power level can be set at 16 power levels, each with a 2 dB increment. The power levels are labeled P(0) to P(15) where P(0) is the highest power level. In TCC mode both TRX:s in the transceiver unit are combined to one signal. In this combination the nominal power level is 49.0 dBm for GMSK and 45.7 dBm for 8-PSK at the antenna connector. The power level can be set at 16 power levels, each with a 2 dB increment. The power levels are labeled P(0) to P(15) where P(0) is the highest power level. 1.5 (7) Maximum Power Rating: The maximum peak power rating with one TRX under environmental and supply voltage variations is equal to 46.3 dBm plus a power level tolerance of + 2.0 dB. Therefore the maximum peak output power is 48.3 dBm equal to 68 W at the antenna connector of the radio base station. Open EXHIBIT 12 3 (10) Prepared (also subject responsible if other) No. ERA/RBI/R Per Helmersson B5KDKRC1311005-2 Approved Checked Date Rev Reference KI/EAB/PJR/IR (P Helmersson) 2006-09-06 A The maximum peak power rating with two TRX.s combined (TCC) under environmental and supply voltage variations is equal to 49 dBm plus a power level tolerance of + 2.0 dB. Therefore the maximum output power with TCC is 52.0 dBm equal to 158 W at the antenna connector of the radio base station. 1.6 (8) Final Amplifier Voltage and Current in normal operation P (0) P (15) Drain Voltage 30 Volt DC 30Volt DC Drain Current 4,3 Amps DC 0,65 Amps DC 1.7 (10) Frequency Stabilizing Circuit Description The transmitter in each TRX contains three synthesized oscillators. One PLL gives a 90 MHz signal to the I/Q modulator. The two other generate a 779 to 804 MHz signal to the mixer where the modulated signal is converted to the transmit frequency. Two oscillators are needed in frequency hopping mode, one is retuning while the other is active. All three synthesized oscillators have a reference of 13 MHz, which is mixed down by 2, generated in a central synthesized oscillator (PLL) of 26 MHz in the LTU part of the dTRU. This PLL frequency reference is extracted from the 13 MHz signal on the Y-link, which is generated and distributed, by the DXU (Distribution Switch Unit), to all dTRU:s in the base station. The frequency reference 13 MHz in the DXU is generated in a voltage controlled oscillator placed in an oven together with and phase-locked to a long-term stable oven heated oscillator. As an option the oscillator can be phase-locked to the incoming PCM-link frequency or an incoming GPS-link frequency. 1.8 (10) Spurious and Harmonic Suppression Spurious and harmonic suppression is achieved by using two separate band pass filters of ceramic type in the exciter. A filter module at the output works like a band pass filter around the carrier. In addition to these filters, the output signal passes a cavity band pass filter in the combining system. 1.9 (10) Limiting Power The TRU measures the output power at its output connector via a RF-detector and the detected value is used by the power loop control block to control two variable gain amplifiers between the modulator and the power amplifier.

This output power is kept as low as possible, by keeping the TRX:s output power in phase with each other, to get maximum output power at the output branch of the hybrid combiner Open EXHIBIT 12 5 (10) Prepared (also subject responsible if other) No. ERA/RBI/R Per Helmersson B5KDKRC1311005-2 Approved Checked Date Rev Reference KI/EAB/PJR/IR (P Helmersson) 2006-09-06 A 1.10 (10) Digital Modulation 1.10.1 Modulation format for GMSK 1.10.1.1 Modulating symbol rate The modulating s…
