Description

The PA48 power amplifier is a discrete hybrid design, which

uses thin film manufacturing processes for accurate

performance and high reliability.

This two stage GaAs FET feedback amplifier design displays

impressive performance characteristics over a broadband

frequency range.

Both TO-8 and Surface Mount packages are hermetically

sealed, and MIL-STD-883 environmental screening is available.
