| GCPW |
grounded
coplanar waveguide |
What
you get when you add a ground plane under the substrate below
CPW. Basically a mixed-mode microstrip/CPW transmission line.
Also called conductor-backed coplanar waveguide (CBCPW). |

maximum gain
|
The theoretical gain
of an amplifier when it is conjugately matched.
|
|
Gopt

One of three noise parameters
for a device, refers to the generator impedance required for
minimum noise figure. Used in noise figure calculations, along
with RN and NFmin.
