Provided are a multiple reflection layer electrode, a compound semiconductor light emitting device having the same and methods of fabricating the same. The elongated member has an inner surface and an outer surface. When at least one of the selected cells has its threshold voltage higher than the pre-verify voltage, a high voltage generator generates a bulk voltage that is increased step by step by a predetermined voltage level. A further aspect of the present invention relates to a bypass valve with a valve body including a plurality of ports and a generally cylindrical inner periphery, as well as a spool seated within the valve body, where the spool is rotatable and axially translatable within the valve body. The ultrawidebande radio transceiverrepeater can be implemented in discrete, integrated, distributed or embedded forms.
