Basic RF System Design
Knowing how much amplification is needed for a system is essential to
designing a successful RF distribution system. This section explains how to
calculate the losses in your system. You should provide enough amplification
to overcome all of the insertion losses of all the system components. If the
signal splits into two branches, each branch must be calculated separately.

Example: Assume a CATV input
signal of 10dBmV. Next, calculate
all the gains and losses of the
components.
