HSMP-381Z
Low Distortion Attenuator RF PIN Diodes
In Surface Mount SOD-323 Package
Data Sheet
Description/Applications
Avago Technologies’ HSMP-381Z is designed for low dis-
tortion attenuator applications. It is housed in a low cost,
industrial standard surface mount package - SOD-323. This
package offers customers who already use them in SOT-
23 and SOT-323 packages, a logical transition to a smaller
package outline to accommodate end product design with
limited board space.
The HSMP-381Z has low distortion and high IP3 charac-
teristics. The device can operate in microwave frequen-
cies and suitable to be used as attenuating circuits in
Infrastructure and CATV applications.
A SPICE model is not available for PIN diodes as SPICE
does not provide for a key PIN diode characteristic --
carrier lifetime.
