MSA-0270 Cascadable Silicon Bipolar MMIC Amplifier Data Sheet Description Features The MSA-0270 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 • 3 dB Bandwidth: DC to 2.8 GHz • 12.0 dB Typical Gain at 1.0 GHz • Unconditionally Stable (k>1) • Hermetic Gold-ceramic Microstrip Package 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. 70 mil Package Typical Biasing Configuration Rbias VCC > 7 V RFC (Optional) 4 Cblock IN Cblock 3 1 OUT MSA 2 Vd = 5 V MSA-0270 Absolute Maximum Ratings Parameter Absolute Maximum[1] Device Current 60 mA [2,3] Power Dissipation 325 mW RF Input Power +13 dBm Junction Temperature200°C Storage Temperature –65 to 200°C Thermal Resistance[2,4]: θjc = 120°C/W Notes: 1. Permanent damage may occur if any of these limits are exceeded. 2. TCASE = 25°C. 3. Derate at 8.3 mW/°C for TC > 161°C. 4. The small spot size of this technique results in a higher, though more accurate determination of θjc than do alternate methods.
