| Up to 6 GHz Medium Power Silicon Bipolar Transistor Technical Data AT-42070 Features * High Output Power: 21.0 dBm Typical P1 dB at 2.0 GHz 20.5 dBm Typical P1 dB at 4.0 GHz * High Gain at 1 dB Compression: 15.0 dB Typical G1 dB at 2.0 GHz 10.0 dB Typical G1 dB at 4.0 GHz * Low Noise Figure: 1.9 dB Typical NFO at 2.0 GHz * High Gain-Bandwidth Product: 8.0 GHz Typical fT * Hermetic Gold-ceramic Microstrip Package 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 up to 1 GHz, makes this device easy to use as a low noise amplifier. The AT-42070 bipolar transistor is fabricated using Hewlett-Packard'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 ionimplantation, self-alignment techniques, and gold metalization in the fabrication of this device. 70 mil Package Description Hewlett-Packard's AT-42070 is a general purpose NPN bipolar transistor that offers excellent high frequency performance. The AT-42070 is housed in a hermetic, high reliability gold-ceramic 70 mil microstrip package. The 4 micron emitter-to-emitter pitch enables this transistor to be used in many 5965-8912E 4-164 AT-42070 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 80 600 200 -65 to 200 Thermal Resistance [2,4]: jc = 150C/W Notes: 1. Permanent damage may occur if any of these limits are exceeded. 2. TCASE = 25C. 3. Derate at 6.7 mW/C for TC > 110C. 4. The small spot size of this technique results in a higher, though more accurate determination of jc than do alternate methods. See MEASUREMENTS section "Thermal Resistance" for more information.
