Description

The A74-2 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
