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, 22.901 (d). 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. This transceiver will in normal mode operate at a nominal output peak power of 45.5 dBm at the antenna connector. The power output is reducible to ~0.3 watts . Due to the too wide frequency spectrum at the band edges in GMSK mode the output power in channel 128 – 869.2 MHz has to be reduced with 4 dB and channel 251 – 893.8 MHz has to be reduced with 3 dB. In 8-PSK mode there is no need to reduce the output power at the band edges. The transceiver has to be used together with a MCPA (separately certified) and a CDU-L which is a unit containing, among other circuits, a filter for the transmitted signal. Ericsson AB requests confidentiality under CFR 0.459. Confidentiality for the following exhibits is requested: Exhibit 5 Part 1 Schematics Exhibit 5 Part 2 Schematics Exhibit 8 Internal manuals Exhibit 9 Internal Photos The Radio Base Station (RBS) is always installed and placed in an area with access only to authorize personal. Sensitive information, such as internal photos and manuals is not available for general public in any form. Only customer with a Non-Disclosure Agreement (NDA) in place will get access to sensitive information. So the only way a competitor could get technical information on the RBS is from FCC records. Justification of this request is in order to protect the large investment in developing this technology and to facilitate the circuit miniaturization utilized in this design and protect the innovative design as well as proprietary techniques, which are implemented. In order to protect Ericsson’s competitive advantage on these proprietary techniques, we request the above listed exhibits be held as confidential and withheld from the Public Information File.

There are 124 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. This combiner is connected before the cavity band pass filter in the combining system. 1.2 (4) Type of Emission: GMSK: 255KGXW 8-PSK: 254KG7W 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 45.5 dBm at the antenna connector. The output signal from the dTRU is amplified in a separately certified MCPA and then filtered in a CDU where the antenna connector is situated. 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 power rating with one TRX under environmental and supply voltage variations is equal to 45.5 dBm plus a power level tolerance of + 1.5 dB. Therefore the maximum peak output power is 47.0 dBm equal to 50 W at the antenna connector of the radio base station.

The output power to the antenna is generated in a separately certified MCPA. P (0) P (15) Drain Voltage 5 V DC 5 V DC Drain Current 80 mA DC 80 mA 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.

T is the symbol period. 1.10.1.2 Start and stop of the burst Before the first bit of the bursts as defined in GSM 05.02 [3] enters the modulator, the modulator has an internal state as if a modulating bit stream consisting of consecutive ones (d i = 1) had entered the differential encoder. Also after the last bit of the time slot, the modulator has an internal state as if a modulating bit stream consisting of consecutive ones (d i = 1) had continued to enter the differential encoder. These bits are called dummy bits and define the start and the stop of the active and the useful part of the burst as illustrated in figure 1. Nothing is specified about the actual phase of the modulator output signal outside the useful part of the burst. dummy bits Output phase The useful part The active part 000..............000 111111..............111111 3 tail bits3 tail bitsdummy bits 1/2 bit1/2 bit Figure 1: Relation between active part of burst, ta…
