Description/Applications
The HSMP-381x series is specifically designed for low dis-
tortion attenuator applications. The HSMP-481x products
feature ultra low parasitic inductance in the SOT-23 and
SOT-323 packages. They are specifically designed for use
at frequencies which are much higher than the upper limit
for conventional diodes.
A SPICE model is not available for PIN diodes as SPICE
does not provide for a key PIN diode characteristic, carrier
lifetime.
