Description
The A87-2 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. Use of an impedance transformer offers the benefit of
high dynamic range and high efficiency.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available
