MSA-9970

Agilent MSA-9970 Cascadable Silicon Bipolar MMIC Amplifier Data Sheet Features Open Loop Feedback Amplifier 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 Description 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. 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. 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. 70 mil Package Typical Biasing Configuration USER SELECTABLE Rf Cf R bias VCC ≥ 10 V RFC (Opt...
