3 / 4 page Low Distortion Attenuator Plastic Packaged PIN Diodes SMP1304 Series Alpha Industries, Inc.

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.
