                                               All the necessary adjustments will be set in the factory, and no adjustments
                                               are needed. The Base Station Controller (BSC) remotely controls the output
                                               power level. If the TRX (one half of dTRU) is not able to maintain the
                                               requirements for power output, frequency stability, etc an alarm is sent to the
                                               BSC. On severe faults the TRX (or TRX:s with TCC function) will disable
                                               transmission.

KI/EAB/RBI/R (P Helmersson)                                                2003-07-31      A




                      3                        2.1033(c)(9,10) Power Tune-Up – Power Limiting
                                               The TRX (one half of dTRU) 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 steer two variable gain amplifiers between the modulator and
                                               the power amplifier.
                                               In TCC (Transmitter Coherent Combining) mode is the output power also
                                               measured with a RF detector in the non-output branch of the hybrid combiner
                                               in the dTRU. 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.
                                               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
                                               longterm stable oven heated oscillator. As an option can the oscillator be
                                               phase-locked to the incoming PCM-link frequency or an incoming GPS-link
                                               frequency.
