4-33 low current, high performance npn silicon bipolar transistor technical data description hewlett-packards at-31011 and at-31033 are high performance npn bipolar transistors that have been optimized for operation at low voltages, making them ideal for use in battery powered applications in wireless markets. the at-31033 uses the 3 lead sot-23, while the at-31011 places the same die in the higher performance 4 lead sot-143. both packages are industry standards compatible with high volume surface mount assembly techniques. the 3.2 micron emitter-to-emitter pitch and reduced parasitic design of these transistors yields extremely high performance products that can perform a mul- tiplicity of tasks. the 10 emitter finger interdigitated geometry yields an extremely fast transistor with low operating currents and reasonable impedances. optimized performance at 2.7 v makes these devices ideal for use in 900 mhz, 1.9 ghz, and 2.4 ghz features ? high performance bipolar transistor optimized for low current, low voltage operation ? 900 mhz performance: at-31011: 0.9 db nf, 13 db g a at-31033: 0.9 db nf, 11 db g a ? characterized for end-of- life battery use (2.7 v) ? sot-143 smt plastic package ? tape-and-reel packaging option available [1] battery operated systems as an lna, gain stage, buffer, oscillator, or active mixer. applications include cellular and pcs handsets as well as industrial-scientific- medical systems. typical amplifier designs at 900 mhz yield 1.3 db noise figures with 11 db or more associated gain at a 2.7 v, 1 ma bias. moderate output power capability (+9 dbm p 1db ) coupled with an excellent noise figure yields high dynamic range for a microcurrent device. high gain capability at 1 v, 1 ma makes these devices a good fit for 900 mhz pager applications. the at-3 series bipolar transistors are fabricated using an optimized version of hewlett-packards 10 ghz f t , 30 ghz f max self- aligned-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, self- alignment techniques, and gold metalization in the fabrication of these devices. at-31011 at-31033 base emitter emitter collector base emitter collector 310 310 sot-23 (at-31033) sot-143 (at-31011) outline drawing note: 1. refer to tape-and-reel packaging for semiconductor devices 5965-8919e
