Description
M/A-COM's AM-191 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 flatpack.
Due to the internal power dissipation the thermal rise
minimized. The ground plane on the PC board should be
configured to remove heat from under the package.
AM-191 is ideally suited for use where a low noise, high
reliability amplifier is required.

2. All specifications apply when operated at +15 VDC, with 50 ohms source and load impedance.
3. Heat Sinking: Operation at case temperature above 95C is not recommended. Heat sinking adequate to dissipate 1.25 W must
be provided in use.
