3.3.6 Fixed TX gain principle
The SAILOR XTR GX-R2 uses a TX IF gain concept. After calibration it provides a fixed
average gain from the TX-port of the BDU to the input of the BUC. Advantages of the
fixed TX IF gain principle are:
• Average TX IF gain independent of antenna cable length
1
• Compatibility with the TX Power control feature
When installing the SAILOR XTR GX-R2 you make a cable calibration. At that point every
installation adjusts to the same average TX IF gain regardless of the ADU cable length.
Additionally the SAILOR XTR GX-R2 system also compensates for variations of the
cable characteristics or loss over frequency.
