GaAs FET AMPLIFIER
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.
