Cascadable Silicon Bipolar MMIC Amplifier Technical Data MSA-9970 MSA-9970 Features Description · Open Loop Feedback Amplifier The MSA-9970 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. · 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 · 16.0 dB Typical Open Loop Gain at 1.0 GHz · 14.5 dBm Typical P1 dB at 1.0 GHz · Hermetic Gold-ceramic Microstrip Package 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. Typical Biasing Configuration USER SELECTABLE Cf Rf R bias VCC 10 V RFC (Optional) 4 C block C block 3 IN OUT MSA 1 2 Vd = 7.8 V 70 mil Package 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. 2 MSA-9970 MSA-9970 Absolute Maximum Ratings Absolute Maximum[1] 80 mA 750 mW +13 dBm 200°C 65°C to 200°C Parameter Device Current Power Dissipation[2,3] RF Input Power Junction Temperature Storage Temperature Thermal Resistance[2,4]: jc = 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 jc than do alternate methods. See MEASUREMENTS section "Thermal Resistance" for more information.
