Description
The RA53 microwave 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.
