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

.
