HIGH POWER PIN DIODES
DESCRIPTION
The UM4000 and UM4900 series features
high power PIN diodes with long carrier
lifetimes and thick I-regions. They are
especially suitable for use in low distortion
switches and attenuators, in HF through S
band frequencies. While both series are
electrically equivalent, the UM4900 series
have higher power ratings due to a shorter
thermal path between the chip and package.
High charge storage and long carrier
lifetime enable high RF levels to be
controlled with relatively low bias current.
Similarly, peak RF voltages can be handled
well in excess of applied reverse bias voltage.
Both series have been fully qualified in high
power UHF phase shifters and megawatt peak-
power duplexers, accumulating thousands of
hours of proven performance. Both types have
been used in the design of antenna selectors and
couplers, where inductance and capacitance
elements are switched in and out of filter or
cavity networks.
