MSA-0420 Cascadable Silicon Bipolar MMIC Amplifier Data Sheet Description Features The MSA-0420 is a high performance silicon bipolar Monolithic Microwave Integrated Circuit (MMIC) housed in a hermetic, high reliability package. This MMIC is designed for use as a general purpose 50Ω gain block. Typical applications include narrow and broad band IF and RF amplifiers in industrial and military applications. • Cascadable 50Ω Gain Block The MSA-series is fabricated using Avago’s 10 GHz fT, 25 GHz fMAX, silicon bipolar MMIC process which uses nitride self-alignment, ion implantation, and gold metallization to achieve excellent performance, uniformity and reliability. The use of an external bias resistor for temperature and current stability also allows bias flexibility. • Hermetic Metal/Beryllia Microstrip Package 200 mil BeO Package Typical Biasing Configuration • 3 dB Bandwidth: DC to 4.0 GHz • 8.5 dB Typical Gain at 1.0 GHz • 16.0 dBm Typical P1 dB at 1.0 GHz • Unconditionally Stable (k>1) R bias VCC > 10 V RFC (Optional) 4 C block IN 3 1 C block OUT MSA 2 Vd = 6.3 V MSA-0420 Absolute Maximum Ratings Parameter Absolute Maximum[1] Device Current 120 mA Power Dissipation[2,3] 850 mW RF Input Power +13 dBm Junction Temperature200°C Storage Temperature –65 to 200°C Thermal Resistance[2,4]: θjc = 40°C/W Notes: 1. Permanent damage may occur if any of these limits are exceeded. 2. TCASE = 25°C. 3. Derate at 25 mW/°C for TC > 166°C. 4. The small spot size of this technique results in a higher, though more accurate determination of qjc than do alternate methods.
