MIXER
The Block Converter uses the Hetrodyne
principle for conversion of a block of S, C or
KU Band frequencies to the IF or
Intermediate Frequencies. The Hetrodyne
principle mixes an external fixed frequency
with the incoming frequency. The output
from the mixer is a series of signals at the
sum and difference of the two inputs to the
mixer. Outputs are also produced at
multiples of these frequencies. A simple filter
is used to suppress all frequency components except those required.
