HSMP-381x, 481x
Surface Mount RF PIN
Low Distortion Attenuator Diodes
Data Sheet
Description/Applications
Features
The HSMP-381x series is specifically designed for low
distortion 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.
• Diodes Optimized for:
– Low Distortion Attenuating
– Microwave FrequencyOperation
A SPICE model is not available for PIN diodes as
SPICE does not provide for a key PIN diode characteristic, carrier lifetime.
• Low Failure in Time (FIT) Rate[1]
• Surface Mount Packages
– Single and Dual Versions
– Tape and Reel Options Available
• Lead-free Option Available
Note:
