AT-41486 Up to 6 GHz Low Noise Silicon Bipolar Transistor Data Sheet Description Features Avago's AT-41486 is a general purpose NPN bipolar transistor that offers excellent high frequency performance. The AT-41486 is housed in a low cost surface mount .085" diameter plastic package. The 4 micron emitter-to-emitter pitch enables this transistor to be used in many different functions. The 14 emitter finger interdigitated geometry yields an intermediate sized transistor with impedances that are easy to match for low noise and moderate power applications. Applications include use in wireless systems as an LNA, gain stage, buffer, oscillator, and mixer. An optimum noise match near 50 at 900 MHz, makes this device easy to use as a low noise amplifier. * Low Noise Figure: 1.4 dB Typical at 1.0 GHz 1.7 dB Typical at 2.0 GHz * High Gain-Bandwidth Product: 8.0 GHz Typical fT * Surface Mount Plastic Package * Tape-and-Reel Packaging Option Available * Lead-free Option Available 86 Plastic Package Pin Connections EMITTER 4 414 The AT-41486 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. * High Associated Gain: 18.0 dB Typical at 1.0 GHz 13.0 dB Typical at 2.0 GHz BASE 1 COLLECTOR 3 2 EMITTER 2 AT-41486 Absolute Maximum Ratings Symbol VEBO VCBO VCEO IC PT Tj TSTG Parameter Emitter-Base Voltage Collector-Base Voltage Collector-Emitter Voltage Collector Current Power Dissipation [2,3] Junction Temperature Storage Temperature Units V V V mA mW C C Absolute Maximum[1] 1.5 20 12 60 500 150 -65 to 150 Thermal Resistance [2,4]: jc = 165C/W Notes: 1.
