1.1 Introduction
The Comtech EF Data (CEFD) Low Noise Amplifier (LNA) series includes LNA and redundant
LNA/LB systems available in C-band (Figure 1-1), X-band (Figure 1-2), Ku-band (Figure 1-3),
and Ka-band (Figure 1-4). They meet or exceed system requirements for commercial
geosynchronous satellites worldwide. Their compact design and rugged construction make them
ideal for transportable applications and severe environments.
The LNAs have a comprehensive set of options to accommodate systems ranging from Very
Small Amplifier Terminals (VSATs) to major earth stations. The redundant LNA/Low-noise Block
Down Converter (LNB) systems include primary and backup LNA(B)s and an automatic
switching controller. The case of primary LNA/LNB failure, fast automatic switchover to the
backup LNA/LNB minimizes downtime.
