Description

The MSA-2085 series are high performance silicon bipolar RFIC amplifiers designed to be cascadable in 50 W systems. The stability factor of K > 1 contributes to easy cascading in numerous narrow and broadband IF and RF commercial and industrial applications.

The MSA-2085 is fabricated using a 10 GHz f_T, 25 GHz FMAX, silicon bipolar RFIC process which utilizes nitride self-alignment, ion implantation, and gold metallization to achieve excellent uniformity, performance, and reliability. The use of an external bias resistor for temperature and current stability also allows bias flexibility.

Package options of MSA-2085 include the industry standard plastic surface mount SOT-143 package, the 100 mil surface mountable hermetic ceramic package, the 85 mil plastic microstripline package, and the 85 mil surface mountable plastic microstripline package.
