SILICON VARACTOR DESCRIPTION
The SMTV and SMTD series of Metelics silicon varactor
diodes are constructed using advanced material
and processes, resulting in a lower series resistance
(R
s
) than is produced with conventional methods.
This lower R
s
results in a higher Q. These diodes are
suitable for applications where the most Q for the dol-
lar is required, since they are competitive with the lower
end of GaAs diodes for Q, while priced as silicon.
