Description
Hewlett-Packard’s AT-42035 is a
general purpose NPN bipolar
transistor that offers excellent
high frequency performance. The
AT-42035 is housed in a cost
effective surface mount 100 mil
micro-X package. The 4 micron
emitter-to-emitter pitch enables
this transistor to be used in many
different functions. The 20 emitter
finger interdigitated geometry
yields a medium sized transistor
with impedances that are easy to
match for low noise and medium
power applications. This device is
designed for use in low noise,
wideband amplifier, mixer and
oscillator applications in the VHF,
UHF, and microwave frequencies.
An optimum noise match near
50␣ Ω up to 1 GHz, makes this
device easy to use as a low noise
amplifier.
35 micro-X Package
The AT-42035 bipolar transistor is
fabricated using Hewlett- Packard’s
10 GHz fT Self-Aligned-Transistor
(SAT) process. The die is nitride
passivated for surface protection.
Excellent device uniformity,
performance and reliability are
produced by the use of ionimplantation, self-alignment
techniques, and gold metalization
in the fabrication of this device.

Thermal Resistance [2,5]:
θjc = 175°C/W
Notes:
1. Permanent damage may occur if any of these limits are exceeded.
2. TCASE = 25°C.
3. Derate at 5.7 mW/°C for TC > 95°C.
4. Storage above +150°C may tarnish the leads of this package making it difficult
to solder into a circuit. After a device has been soldered into a circuit, it may
be safely stored up to 200°C.
5. The small spot size of this technique results in a higher, though more
accurate determination of θjc than do alternate methods. See MEASUREMENTS section “Thermal Resistance” for more information.
