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.
