Figure 2: RX-1939 System Diagram

As shown in the above figure, the downlink BS signals go through DT port to the system and then todownlink by duplexer separation. The DL signals will go through DT duplexer then to digital RF monitoringmodule for digital filtering and self-oscillation elimination. Then the DL signals will be sent to downlink PAto amplify power and filter via duplexer. After amplification, the signals are transmitted at the MT port to

the service antenna.

On the UL, the signals transmitted by the mobile go through MT integration duplexer and digital RFmonitoring module then to uplink PA to power amplify and filter via duplexer, finally get back to BS bydonor antenna.

7. Test coverage area fieldintensity and adjustservice antenna.

Use test-handset to verify field intensity within the coverage area. Ifneeded, realign the service antenna to achieve the desiredcoverage.

Note: If during operation, the equipment gain could not be set tomaximum or the output power is not high enough due to insufficientdonor and service antennas isolation, then the antennas positionshould be changed to increase isolation. If the output power is toohigh and ALC is activated, then adjust the DL ATT to achieveoptimal DL Gain.

8. Verify UL gain and ensuretest call produces goodvoice quality and there isno interfering BTS

Adjust UL gain and perform test calls. Typically, the UL gain is setaround 5dB less than DL gain. Perform test calls in the coveragearea while adjusting UL gain if required.

Note: If the repeater is near the BTS and the test call performanceis poor, this may be due to UL noise interference to the BTS. Userscan calculate and determine if the repeater UL noise will interferewith the BTS.

Verify again that there is no unacceptable interference to BTS.
