Appendix E
Optional L-Band BUC
E.1 Overview
The L-Band RF input signal is converted by the Block Up-Converter (BUC) to the frequency
band of the amplifier.
Each amplifier is provided with a label indicating the correct L-Band input frequencies accepted
by the BUC. This label is shown in figure E-1. The bandwidth of the L-Band input frequency is
typically the same bandwidth as the amplifier's output frequency bandwidth.
Warning: Ensure that the proper L-band frequency range is not exceeded
or damage may result. Damage due to an improper frequency input may
not be covered in the warranty of the amplifier.
This appendix provides information on BUC operation and explains the three types of
frequency references which can be used.

Note: Refer to the amplifier specifications in the "Drawings" chapter for
performance of the amplifier with a BUC.
