Low Distortion Attenuator Plastic Packaged PIN Diodes
Resistance vs. Temperature @ 100 MHz
SMP1304-007
In the -007 configuration of the SOT-23 package, the
package inductance is effectively reduced to 0.4 nH, in
comparison to the 1.5 nH value of the standard
configuration. This lower inductance will be particularly
beneficial when the diodes are used as shunt connected
switches at frequencies higher than 500 MHz, where
inductance is the primary limitation on maximum switch
isolation.
To achieve the effective 0.4 nH, the SOT-23 package must
be inserted in the microstrip circuit board with a gap in the
trace, as shown in the figure. Because of the polarity of
the diode junction, this low inductance feature is only
realizable with the cathode connected to ground.

SMP1304-019 PI Attenuator PIN Diodes
The SMP1304-019 employ three PIN diode junctions in
a SOT-143 package. They are configured for ease of
insertion in PI attenuator circuits commonly used from 10
MHz to beyond 1 GHz. The SMP1304 PIN diode junction
was designed for low capacitance, wide resistance
dynamic range and low distortion performance.
