Agilent MSA-0470 Cascadable Silicon Bipolar MMIC Amplifier Data Sheet
Features
• Cascadable 50 Ω Gain Block • 3 dB Bandwidth: DC to 4.0 GHz
Description
The MSA-0470 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 50 Ω gain block. Typical applications include narrow and broad band IF and RF amplifiers in industrial and military applications. The MSA-series is fabricated using Agilent’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.

MSA-0470 Absolute Maximum Ratings
Parameter Device Current Power Dissipation[2,3] RF Input Power Junction Temperature Storage Temperature Absolute Maximum[1] 100 mA 650 mW +13 dBm 200°C –65 to 200°C Thermal Resistance[2,4]: θjc = 115°C/W
Notes: 1. Permanent damage may occur if any of these limits are exceeded. 2. TCASE = 25°C. 3. Derate at 8.7 mW/°C for TC > 125°C. 4. The small spot size of this technique results in a higher, though more accurate determination of θjc than do alternate methods.
