Description
M/A-COM’s AM-146 is a coupler feedback amplifier with
high intercept and compression points. The use of coupler
feedback minimizes current in a high intercept amplifier.
This amplifier is packaged in a flatpack with flanges. Due
to the metal flatpack the thermal rise minimized. The
ground plane on the PC board should be configured to
remove heat from under the package. AM-146 is ideally
suited for use where a high intercept, high reliability
amplifier is required.

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