•Unconditionally Stable (k>1)
•Cost Effective Ceramic Microstrip Package
Description
The MSA-0235 is a high performance silicon bipolar Monolithic Microwave Integrated Circuit (MMIC) housed in a cost effective, microstrip 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 HP’s 10 GHz fT, 25Ê GHz MAXf , 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.
Available in cut lead version (package 36) as MSA-0236.

2.TCASE = 25°C.
3.Derate at 6.9 mW/°C for TC > 153°C.
4.Storage above +150°C may tarnish the leads of this package making it difficult to solder into a circuit.
5.The small spot size of this technique results in a higher, though more accurate determination of θjc than do alternate methods. See MEASUREMENTS section “Thermal Resistance” for more information.
