Description
M/A-COM's AM-155 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 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-155 is ideally suited for use where a high intercept,
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 0.9W must
be provided in use.
