Description
Agilent鈥檚 AT-41532 is a general
purpose NPN bipolar transistor
that has been optimized for
maximum f
t
at low voltage
operation, making it ideal for use
in
battery powered
applications in cellular/PCS
and other wireless markets.
The AT-41532 uses the miniature
3-lead SOT-323 (SC-70) plastic
package.
Optimized performance at 5 V
makes this device ideal for use in
900 MHz, 1.8 GHz, and 2.4 GHz
systems. Typical amplifier design
at 900 MHz yields 1 dB NF and
15.5 dB associated gain at 5 V and
5 mA bias. High gain capability at
1 V and 1 mA makes this device a
good fit for
900 MHz pager
applications.
A good noise
match near 50 ohms at 900 MHz
makes this a very user-friendly
device. Moreover, voltage
breakdowns are high enough to
support operation at 10 V.
The AT-41532 belongs to Agilent鈥檚
AT-4XXXX series bipolar
transistors. It exhibits excellent
device uniformity, performance,
and reliability as a result of ion-
implantation, self-alignment
techniques, and gold metalization
in the fabrication process.
