Description

The A77 RF amplifier is a discrete hybrid design,

which uses thin film manufacturing processes for

accurate performance and high reliability. The 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.
