Description
Hewlett-Packard's AT-41511 and AT-41533 are general purpose NPN bipolar transistors that offer excellent high frequency performance at an economical price. The AT-41533 uses the 3 lead SOT-23, while the AT-415 11 places the same die in the lower parasitic 4 lead SOT-143. Both packages are industry standard, and compatible with high volume surface mount assembly techniques. The 4 micron emitter-to-emitter pitch of these transistors yields high performance products that can perform a multiplicity of tasks. The 14 emitter finger interdigitated geometry yields an intermediate-sized transistor with easy to match to impedances, low noise figure, and moderate power. Optimized for best performace from a 5 to 8 volt bias supply, these transistors are also good
performers at 2.7 V. Applications include use in wireless systems as an LNA, gain stage, buffer, oscillator, or active mixer. An optimum noise match near 50 ohms at 900 MHz makes these devices particularly easy to use as LNAs. Typical amplifier designs at 900 MHz yield 1 dB noise figures with 15 dB or more associated gain at a 5 V, 5 mA bias, with good gain and noise figure obtainable at biases as low as 2 mA. The AT-415 series bipolar transistors are fabricated using Hewlett-Packard's 10 GHz fT SelfAligned-Transistor (SAT) process. The die are nitride passivated for surface protection. Excellent device uniformity, performance and reliability are produced by the use of ion-implantation, selfalignment techniques, and gold metalization in the fabrication of these devices.
