[EN] Unilateral transducer constant power gain circles play an essential role
in the design of radio-frequency amplifiers and active modulators, as
they help to determine optimal impedance matching conditions to
meet gain and stability specifications. It is shown that these gain
circles are a subfamily of Apollonius circles. For better visualisation,
unilateral transducer constant gain power circles have been plotted
for the first time on the three-dimensional (3D) Smith chart. To this
end, a natural relationship from an inversive geometry was required,
in order to relate the gain circles with cutting planes for the 3D
Smith chart.
