Description
The A25-1 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. Both TO-8 and Surface Mount packages are
hermetically sealed, and MIL-STD-883 environmental screening
is available.
