Description
The EA54 RF amplifier is a discrete hybrid design, which uses
thin film manufacturing processes for accurate performance and
high reliability.
This single stage bipolar transistor feedback amplifier design
displays impressive performance over a broadband frequency
range. The unit is packaged in a TO-5 hermetically sealed, and
MIL-STD-883 environmental screening is available.
