Description
M/A-COM’s AM-147 is a coupler feedback amplifier with high
intercept and compression points. The use of coupler feedback
minimizes noise figure and current in a high intercept amplifier.
This amplifier is packaged in a TO-8 package. Due to the inter-
nal power dissipation the thermal rise minimized.
The ground
plane on the PC board should be configured to remove heat from
under the package. AM-147 is ideally suited for use where a high
intercept, high reliability amplifier is required.
