3. AP 3.1 AP-RFU 3.1.1 Overview The AP-RFU consists of three blocks: Antenna section, RF section and IF section. • Antenna section The omni-directional antenna (with horizontal directivity of 360°) and the horn-type antenna ( 90° × 10° directivity) give same shapes of AP-RFU. • RF section In the RF section, the transmission IF signals are up-converted into 24-26 GHz-band RF signals using the local signal, which is generated by multiplying the 2.4 GHz synthesized oscillator. The next-stage BPF eliminates unwanted sideband components. The up-converted 24-26 GHz-band RF signals are amplified up to the desired level then fed to the antenna via the TDD-Switch and the Waveguide Filter. The received 24-26 GHz-band RF signals by the antenna are fed in to the LNA via the Waveguide Filter and the TDD-Switch. The output signals of the LNA are down-converted into IF signals using the local signal, which is generated by multiplying the 2.4 GHz synthesized oscillator. The BPF is employed to eliminate the image components (interference). The TDD Switch selects the transmitting or receiving function. Detection of the transmiting burst at the IF section turns the switch to the transmiting side. • IF section In the receiving IF section, the output level to the AP-IFU is adjusted by the automatic gain control (AGC) function, so that the input level of the AP-IFU does not saturate for the reception of the WT signal which gives highest receiving level. The SAW filter eliminates the adjacent channel interference. In the transmitting IF section, the detection of the transmiting burst signal control the TDD-Switch in the RF section to turn it to the transmiting side. The SAW filter provides the signal delay for the period of the burst detection and the TDD-Switch turning time, as well as the elimination of the non-desired signal component. The IF section also has the compensation functionarity for cable losses between the AP-RFU and AP-IFU. The CPU in the IF section performs the AGC, the cable loss compensation , and the monitoring and control functionalities. Figure 3-1 is a block diagram of the AP-RFU.
3-13 Figure 3-1 AP-RFU Block Diagram 3.1.2 Operations and Indications The AP-RFU does not have any operation or indication panels. 3.2 AP-IFU 3.2.1 Overview AP-IFU consists of three blocks: IF section, digital section and interface section. • IF section The transmission IF section performs quadrature modulation of 427.5MHz IF frequency according to the transmission output from the digital modem installed in the WT-ASIC. In the receiving IF section, the received burst signal level is adjusted by the automatic gain control (AGC) function of the digital modem. The quadrature demodulator downconverts the received IF signal into the baseband signal. The digital section consists of a digital modem, TDD/TDMA framer, wireless MAC processor, and system controller. These functionarities are equipped in the WT-ASIC. The digital modem performs modulation and demodulation of transmitting and receiving burst signals. The interface section has an interface between the AP and the upper unit (100BASE-TX). It provides a 100BASE-FX interface by installing the AP optical INTF unit. to IFUAP-RFUWGBPFRFSWLNASW2.4GHzSynth26G:×10×n×2DOWN_CONVTRSEL(RF)PA×2UP_CONVFREQ_CNTIF部HYBASKMODEMTempCNT D/AD/AAGC×2HYB1282.5MHzATPCAGC213.75MHzMAX_HOLD/AVERAGING A/DTRCNTVariable[20dB]TempCNTRFU￨IFUContTemp SensVAR_ATT[30dB]CABLELOSSDC+16VLOGAMPTMGGenCOMP THCNTObstacleinformationTRSEL(RF)FREQ_CNT[DATLCLK/LE]427.5MHzSAW BPFIF_Freq1710MHzSAW BPFHornAntenna(V/H)orOmniAntenna(V/H)×3BPFSAWBPFIRFDielectric_BPFLOGAMPSAW_BPFAGC2RX_LVLCNTAUTO ON/OFFAGC2RFU-IFAP-RFU_PSSerge protectionCoaxCABLE
3-14 The digital section consists of the wireless MAC processor, TDD/TDMA controller, modem and system controller. The wireless MAC processor converts between the Ethernet frames that the interface section handles and wireless MAC frames. It also schedules the dynamic slot assignment. The TDD/TDMA controller performs scrambling, encryption, error correction and other processing. The system controller performs operating parameter setting, state monitoring, control and testing for the modem, TDD/TDMA processor, wireless MAC processor and network interface. It also sends and receives maintenance signals via SNMP. It performs delay control, authentication and other procedures, operating parameter setting, state monitoring, control and testing for the subordinate WTs over a DMF channel. The transmission IF section in the IF section performs quadrature modulation for the transmission baseband signals at 427.5MHz LOC frequency for upconversion to IF signals. It also controls the output level to the desired level based on the control from the ASIC.

4-17 4. WT 4.1 WT 4.1.1 Overview The WT consists of the antenna section, RF section, IF section, digital section, interface section and power supply. • Antenna section Uses a Triplate planar antennas to make the antenna compact and to provide a high gain. • RF section In the RF section, the transmission IF signals are up-converted into 24-26 GHz-band RF signals using the local signal, which is generated by multiplying the 2.4 GHz synthesized oscillator. The next-stage BPF eliminates unwanted sideband components. The up-converted 24-26 GHz-band RF signals are amplified up to the desired level then fed to the antenna via the TDD-Switch and the Waveguide Filter. The received 24-26 GHz-band RF signals by the antenna are fed in to the LNA via the Waveguide Filter and the TDD-Switch. The output signals of the LNA are down-converted into IF signals using the local signal, which is generated by multiplying the 2.4 GHz synthesized oscillator. The BPF is employed to eliminate the image components (interference). The TDD Switch selects the transmitting or receiving function under the control of TDD/TDMA framer installed in the WT-ASIC. • IF section The transmission IF section performs quadrature modulation of 427.5MHz IF frequency according to the transmission output from the digital modem installed in the WT-ASIC. The SAW filter in the next stage eliminates undesired out-of-band signals. The output level of the transmission IF secton is adjusted by the automatic transmission gain control (ATPC) function of the digital modem. . In the receiving IF section, the SAW filter eliminates the adjacent channel interference. The received burst signal level is adjusted by the automatic gain control (AGC) function of the digital modem. The quadrature demodulator downconverts the received IF signal into the baseband signal. • Digital section The digital section consists of a digital modem, TDD/TDMA framer, wireless MAC processor, and system controller. These functionarities are equipped in the WT-ASIC.
4-18 The digital modem performs modulation and demodulation of transmitting and receiving burst signals. The TDD/TDMA framer constructs and deconstructs radio burst frames. It alse performs scrambling, encryption, and error correction functionarities. The wireless MAC processor converts between the Ethernet frames and the wireless MAC frames in the radio channel. The system controller performs operating parameter setting, state monitoring, control and testing for the entire unit. It also communicate with the AP processer via the DMF channel. • Interface section The interface section provides the physical interrfaces of Ethernet for user interface and serial interface for the receiving level measurement terminal. It has a lightning surge protector to protect the unit against external surges. • Power supply The power supply section generates various voltages used within the unit from +24V input power.
