Description/Applications
The HSMP-381B/C/E/F series is
specifically designed for low
distortion attenuator applications.
The HSMP-386B/C/E/F series is a
general purpose PIN diode
designed for low current attenua-
tors and low cost switches. The
HSMP-389B/C/E/ F series is
optimized for switching applica-
tions where low resistance at low
current, and low capacitance are
required.
The HSMP-48XB series is special
products featuring ultra low
parasitic inductance in the SOT-
323 package, specifically designed
for use at frequencies which are
much higher than the upper limit
for conventional SOT-323 PIN
diodes. The HSMP-481B diode is a
low distortion attenuating PIN
designed for operation to 3 GHz.
The HSMP-482B diode is ideal for
limiting and low inductance
switching applications up to
1.5 GHz. The HSMP-489B is
optimized for low current switch-
ing applications up to 3 GHz.
