MSA-3111, MSA-3186
Silicon Bipolar RFIC Amplifiers
Data Sheet
Description
Features
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.
MSA-3111
• Surface Mount SOT-143 Package
• 3 dB Bandwidth: DC to 0.5 GHz
• 18.4 dB Gain at 1 GHz
• 3.5 dB NF at 1 GHz
• Lead-free Option Available
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 flexibility.
Package options include the industry standard plastic
surface mount SOT-143 package and the 85 mil surface
mountable plastic microstripline package.
MSA-3186
• Surface Mount Plastic Microstrip Package
• 3 dB Bandwidth: DC to 0.5 GHz
• 18.7 dB Gain at 1 GHz
• 3.5 dB NF at 1 GHz
• Lead-free Option Available
