PIN DIODE
SWITCHING DIODE-Ceramic Surface Mount
RoHS Compliant Version Available
KEY FEATURES
DESCRIPTION
With high isolation, low loss, and low distortion characteristics, this
Microsemi ceramic package PIN diode is perfect for two-way radio
antenna switch applications where size and power handling
capability are critical. The surface mount package is ideal for high
volume automated assembly applications.
. High Power Surface Mount
Package.
. Specified low distortion, low
loss.
Its advantages also include the low forward bias resistance and
high zero bias impedance that are essential for low loss, high
isolation, and wide bandwidth antenna switch performance. Its
square design makes this device ideal for use with automatic
insertion equipment.
. Low bias current requirements.
. High zero bias impedance.
. Low inductance and
capacitance.
. Compatible with automatic
insertion equipment.
. RoHS compliant packaging
