HSMP-386D
PIN Diode Diversity Switch
Data Sheet
Description
The HSMP-386D is a low cost and high linearity diversity
switch designed to operate from 50MHz to 6GHz.
HSMP-386D is built with unique 4 PIN diode configuration,
and it is housed in a industrial standard low cost miniature
SOT-143 package, which will allow board space saving for
space constraint application.
HSMP-386D is equipped with -0.35dB IL and -25.40dB
ISO @ 900MHz. On the other hand, HSMP-386D is also
featuring with 56.83dBm IIP3 and 47.41dBm IP1dB per-
formance @ 900MHz. HSMP-386D is suitable for wireless
application that required low distortion diversity switch,
such as dect phone, wireless LAN and WiMAX.
