They are especially suitable for use in low distortion switches and attenuators, in HF through S band frequencies. While both series are Power dissipation to 37.5 W 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 Series resistance rated at 0.5 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 Carrier lifetime greater than 5 s voltage. Both series have been fully qualified in high power UHF phase shifters and megawatt Non cavity design peak-power duplexers, accumulating thousands of hours of proven performance. Both types have been used in the design of antenna selectors and couplers, where RoHS compliant version 1 inductance and capacitance elements are switched in and out of filter or cavity available networks. The standard finish for the UM4000 series is Sn/Pb. For RoHS compliant devices, Thermally matched configuration use the UMX prefix. (IE: UMX4000SM) The UMX series meets RoHS requirements per EU Directive 2002/95/EC.
