SILICON MULTIPLIER DESCRIPTION
The SMMD series of Metelics Multiplier Diodes are
constructed using advanced material and pro-
cesses, resulting in a lower series resistance (R
s
) than
is produced with conventional methods. This lower
R
s
results in faster transition times and higher output
frequencies. The lower R
s
also reduces loss and there-
fore results in higher efficiency.
Also available in SOT23 package.
