C-Band (with High-Side Injection) follows similar frequency conversion as
Ku-Band, except for the following: the effect of the High-Side Injection will
invert the L-Band spectrum in relation to the RF and IF spectrums. [This ex-
hibits that the beginning of transponder has a lower frequency than the end of
the transponder at RF and IF, but the opposite will be true at L-Band; the be-
ginning will be a higher frequency than the end of the transponder.]
