2.4.4 LNA, LNB, and Waveguide Pinouts
LNAs and LNBs can be supplied with three different connector configurations, depending on the model and
options. The most common LNA/LNB pinouts are 3-, 4- and 6-pin.
Waveguide connectors are always 6-pin, but vary in size, depending on the frequency of the switch (C-band, X-
band, S-band, and Ku-band). See Table 2-4 for pinouts of the above connectors.
