7.3.2 Procedure
1. Remove the 8x T20 screws from the perimeter of the radio.
2. Pull the 2 clamshell halves away from each other, separating them at the interface end and pivoting at the other end.
Ensure that you don’t lose the two small O-ring seals which sit on chassis pillars as shown above.
3. Disconnect the 4x SMB connectors from the RF Board. Long nose pliers are the best tool to remove the connectors
otherwise it can be difficult to grip the connector. Don’t simply pull or leaver up the cable as this will damage the coax
at the SMB interface. You can use the SMB connectors on the semi-flexible coax as the test interface by using the
appropriate SMB male adapter. This can be more convenient than removing the entire duplexer from the chassis.
4. Calibrate/set up the network analyser to the desired frequency band. It helps to limit the source power to -15dBm so
as not to overload the LNA in the Rx path.
Channel 1 and 2 Duplexer
7.3.2.1 To Calibrate the TX Side
1. Refer to the above figure. Connect Port 1 to TX Port, connect Port 2 to Antenna Port, Connect 50ohm Load to Rx
Port, Connect +5V (If you keep the duplexer in the chassis, with +5V connected, you can use the radio +5V by
powering the radio unit during calibration).
2. Ensure TX and Rx duplexer is completely detuned away from the frequency of operation.
