GaAs FET DESIGN
Description
The A45 RF amplifier is a discrete hybrid design, which uses
thin film manufacturing processes for accurate performance
and high reliability.
This single stage GaAs FET feedback amplifier design displays
impressive performance characteristics over a broadband
frequency range. An RF choke is used for DC power supply
decoupling.
Both TO-8 and Surface Mount packages are hermetically
sealed, and MIL-STD-883 environmental screening is available.
