LNA feed and BUC feed pin assignment for different module types
The function of J4 pins described as LNA_feed and BUC_feed can vary dependant on the module type. The table below shows pin
assignment for all different module types.
The “X” used on the pin assignment indicates the slot to which the LNA or BUC feed is connected (i.e. LNA_feed_8 is connected to slot 8).
When an “A” or “B” suffix is shown this is used to indicated which channel of the dual module (i.e. “LNA_feed_A_X” or the LNA or BUC feed)
is connected to, it will match with the connector letter on the rear panel
. Channel “A” is the upper channel and channel “B” is the lower
channel. Transceivers always have the receiver as the upper channel and the transmitter as the lower channel.
The LNA and BUC feed will only be connected if the module in the slot has the appropriate functionality.
