DuplexerThe duplexer consists of a RX filter and a TX filter. The duplexer provides a reliable channelfor both RX signals and TX signals sharing one antenna, ensuring that the strong TX signalswill not affect weak RX signals.

Cavity CombinerIt provides dual two-in-one mechanism to be cascaded with the DFCU.

LNAThe LNA amplifies RX signals sent from the antenna. You can run the commands on the BTSto control the gain of the LNA. The LNA features self-detection through which an alarm isreported when a fault occurs.

Control UnitThe control unit controls the combiner, detects the VSWR alarm, sets the LNA gain, detects theLNA alarm, and sets up the communication between the DFCU and the BTS.

Directional CouplerThe directional coupler features VSWR detection. The VSWR testing circuit checks the forward/reverse DL power through the standing-wave detector. The output voltage from the standing-wave detector are processed and calculated. If the VSWR exceeds a specified threshold, theVSWR alarm is reported.

Duplexer

The duplexer consists of a RX filter and a TX filter. The duplexer provides a reliable channelfor both RX signals and TX signals sharing one antenna, ensuring that the strong TX signalswill not affect weak RX signals.

Cavity Combiner

Micro-Band Combiner

Combining two routes of signals from the cavity combiner into one route

LNA

The LNA amplifies RX signals sent from the antenna. You can run the commands on the BTSto control the gain of the LNA. The LNA features self-detection through which an alarm isreported when a fault occurs.

Diversity Filter

The diversity filter filters the signals from the diversity ports.




Control UnitThe control unit controls the combiner, detects the VSWR alarm, sets the LNA gain, detects theLNA alarm, and sets up the communication between the DFCU and the BTS.

Directional CouplerThe directional coupler features VSWR detection. The VSWR testing circuit checks the forward/reverse DL power through the standing-wave detector. The output voltage from the standing-wave detector are processed and calculated. If the VSWR exceeds a specified threshold, theVSWR alarm is reported.

DBRUThe DBRU is the main functional module of the DTRU. The DBRU performs modulation/demodulation, data processing, and combining/dividing between the baseband signals and theRF signals.

DPAUThe DPAU performs the following functions:

l Amplifying the TX signals transmitted from the DBRU to the required level

l Coupling the output power for loopback test and power detection

l Detecting the temperature of the power amplifier

l Supporting wideband combination and PBT functions

DTPSThe DTPS is the power supply board of the DTRU. The DTPS converts the –48 V DC powersupply into +28 V DC for the DPAU. The DTPS also supplies three routes of power requiredby the TRX: 8 V, 4 V, and 3.3 V.




RF Transmit Model In transmit independency mode, the two TRXs are used independently without using the

combination unit. Figure 4-38 shows the transmit independency mode.

l In PBT mode, only one TRX in the DTRU is used. One route of signals goes throughmodulation and DA conversion. Then, the converted RF signals are divided into two routesand sent to the power amplified for amplification. At last, the amplified signals arecombined. Because these two routes of signals are aligned in phase, combination results intheir power amplification. Figure 4-39 shows the working principles in the PBT mode.
