Features
* Usable Gain to 6.0 GHz * High Gain: 32.5 dB Typical at 0.1 GHz 22.5 dB Typical at 1.0 GHz * Low Noise Figure: 3.3 dB Typical at 1.0 GHz * Low Cost Plastic Package
purpose 50 gain block above 0.5 GHz and can be used as a high gain transistor below this frequency. Typical applications include narrow and moderate band IF and RF amplifiers in commercial and industrial applications. The MSA-series is fabricated using HP's 10 GHz fT, 25 GHz f MAX, 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.
