Description
The MSA-31XX series are high performance silicon bipolar RFIC amplifiers designed to be cascadable in 50 Ω systems. The stability factor of K > 1 contributes to easy cascading in numerous narrow and broadband IF and RF commercial and industrial applications. The MODAMP MSA series is fabricated using a 10 GHz fT, 25 GHz FMAX, silicon bipolar RFIC process which utilizes nitride selfalignment, 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 include the industry standard plastic surface mount SOT-143 package and the 85 mil surface mountable plastic microstripline package.
