• Low Series Resistance
• Low Capacitance
Description/Applications
These general purpose switching
diodes are intended for low
power switching applications
such as RF duplexers, antenna
switching matrices, digital phase
shifters, and time multiplex
filters. The 5082-3188 is
optimized for VHF/UHF
bandswitching.

The RF resistance of a PIN diode
is a function of the current
flowing in the diode. These
current controlled resistors are
specified for use in control
applications such as variable RF
attenuators, automatic gain
control circuits, RF modulators,
electrically tuned filters, analog
phase shifters, and RF limiters.
Outline 15 diodes are available on
tape and reel. The tape and reel
specification is patterned after
RS-296-D.

Mechanical
Specifications
The Agilent Outline 15 package
has a glass hermetic seal with
dumet leads. The lead finish is 95-
5 tin-lead (SnPb) for all PIN
diodes. The leads on the Outline
15 package should be restricted
so that the bend starts at least 1/
16 inch (1.6 mm) from the glass
body. Typical package inductance
and capacitance are 2.5 nH and
0.13 pF, respectively. Marking is
by digital coding with a cathode
band.
