The RA89 RF amplifier is a discrete hybrid design, which uses
thin film manufacturing processes for consistent performance
and high reliability.
This 2 stage bipolar transistor feedback amplifier design
displays impressive performance over a broadband
frequency range. An active DC biasing network insures
temperature-stable performance.Both TO-8B and Surface
Mount packages are hermetically sealed, and
MIL-STD-883 environmental screening is available.
