Description
Avago’s AT-42036 is a general purpose NPN bipolar tran-
sistor that oers excellent high frequency performance.
The AT-42036 is housed in a cost eective surface mount
100 mil micro-X package. The 4 micron emitter-to-emitter
pitch enables this transistor to be used in many dierent
functions. The 20 emitter nger interdigitated geometry
yields a medium sized transistor with impedances that
are easy to match for low noise and medium power ap-
plications. This device is designed for use in low noise,
wideband amplier, 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 amplier.
The AT-42036 bipolar transistor is fabricated using
Avago’s 10 GHz fT Self-Aligned-Transistor (SAT) process.
The die is nitride passivated for surface protection.
Excellent device uniformity, performance and reliabil-
ity are produced by the use of ion-implantation, self-
alignment techniques, and gold metalization in the fabri-
cation of this device.

Thermal Resistance[2,5]:

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 dicult to solder into
a circuit.
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.
