DESCRIPTION
Avago’s 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 AT31033 uses the 3 lead SOT‑23, while The 3.2 micron emitter-to-emitter pitch and reduced parasitic design of these transistors yields extremely high performance products that can perform a multiplicity 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 battery operated systems as an LNA, gain stage, buffer, oscilla tor, 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 P1dB) coupled with an excellent noise figure yields high dynamic range for a microcurrent device.
