Description
The A74-1 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-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available
