Description
The A25-1 RF amplifier is a discrete hybrid design, which
uses thin film manufacturing processes for accurate per-
formance and high reliability.
This single stage bipolar transistor feedback amplifier de-
sign 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.
