Description
The MP4T645 family of high gain-bandwidth, small
signal silicon bipolar transistors is well suited for use in
amplifiers to approximately 4 GHz, and in oscillators to
approximately 10 GHz. These industry standard transis-
tors freature low noise figure at high collector current,
which produces v ery good associated gain and wide
dynamic range. The MP4T645 series transistors are
av ailable
in
a
hermetic
microstrip
package
(MP4T64535), in the plastic SOT-23 package
(MP4T64533), in chip form (MP4T64500), and in the
SOT-143 package (MP4T64539). The MP4T645 series
is av ailable in other plastic and hermetic packages as
well. The chip and hermetically packaged transistors
can be screened to a JANTXV equiv alent lev el.

Applications
The MP4T645 family of bipolar NPN transistors can be
used for low noise, high associated gain. large dynamic
range amplifiers up to approximately 4 GHz. These
transistors can also be used as preamplifier or driv er
stages in the same frequency range.
The MP4T645 family of bipolar NPN transistors can also
be used for oscillators or VCOs up to approximately 10
GHz.
The passiv ation consists of silicon dioxide,
commonly known as thermal oxide, and silicon nitride to
produce v ery low 1/f noise in both amplifiers and
oscillators.
