AT-42035

AT-42035 Up to 6 GHz Medium Power Silicon Bipolar Transistor Data Sheet Description Avago Technologies' AT-42035 is a general purpose NPN bipo lar 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. The AT-42035 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 reliability are produced by the use of ion-implantation, self-alignment techniques, and gold metalization in the fabrication of this device.

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. 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.
