MSA-9970 Cascadable Silicon Bipolar MMIC Amplifier Data Sheet Description Features The MSA-9970 is a high performance silicon bipolar Monolithic Microwave Integrated Circuit (MMIC) housed in a hermetic high reliability package. This MMIC is designed with high open loop gain and is intended to be used with external resistive and reactive feedback elements to create a variety of special purpose gain blocks. • Open Loop Feedback Amplifier Applications include very broadband, minimum ripple amplifiers with extended low frequency performance possible through the use of a high valued external feedback blocking capacitor; extremely well matched (–20 dB return loss) amplifiers; and negative gain slope amplifiers for flattening MMIC cascades. • 16.0 dB Typical Open Loop Gain at 1.0 GHz • Performance Flexibility with User Selected External Feedback for: Broadband Minimum Ripple Amplifiers Low Return Loss Amplifiers Negative Gain Slope Amplifiers • Usable Gain to 6.0 GHz • 14.5 dBm Typical P1 dB at 1.0 GHz • 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 USER SELECTABLE Cf Rf R bias VCC ≥ 10 V RFC (Optional) 4 C block IN 1 C block MSA 2 3 OUT Vd = 7.8 V MSA-9970 Absolute Maximum Ratings Parameter Absolute Maximum[1] Device Current 80 mA [2,3] Power Dissipation 750 mW RF Input Power +13 dBm Junction Temperature200°C Storage Temperature –65°C to 200°C Thermal Resistance[2,4]: θjc = 150°C/W Notes: 1. Permanent damage may occur if any of these limits are exceeded. 2. TCASE = 25°C. 3. Derate at 6.7 mW/°C for TC > 88°C. 4. The small spot size of this technique results in a higher, though more accurate determination of θjc than do alternate methods.
