UM4000 / UM4900
HIGH POWER PIN DIODES
RoHS Compliant Versions Available
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.
The standard finish for the UM4000 series is Sn/Pb. For RoHS compliant devices,
use the UMX prefix. (IE: UMX4000SM) The UMX series meets RoHS requirements
per EU Directive 2002/95/EC.
