3.3.2
Due to the use of a SAW filter for mixer input matching and balancing an isolated
measurement of the mixer figures is not possible. The following system calculations
have valid entries only for the Gain, IP3, and Noise Figure. The input values are either
from extra measurements (e.g. SAW filter insertion loss) or adjusted to give a cascade
figure that can be measured (e.g. filter+mixer IP3). All non-fat typeface figures have no
meaning.
