Description
The MSA-31XX series are high performance silicon bi-
polar RFIC ampliers 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 self-alignment, ion implantation, and gold metalli-
zation to achieve excellent uniformity, performance, and
reliability. The use of an external bias resistor for tem-
perature and current stability also allows bias exibility.
Package options include the industry standard plastic
surface mount SOT-143 package and the 85 mil surface
mountable plastic microstripline package.
