Description

M/A-COM’s AM-138 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

with flanges. Due to the internal power dissipation the

thermal rise should be minimized. The ground plane on the

PC board should be configured to remove heat from under

the package. AM-138 is ideally suited for use where a high

intercept, high reliability amplifier is required.

2. Bias may be applied to either a single bias pin, or both

bias pins. If bias is applied to both bias pins, it is impor-

tant that potential ground loops be avoided, and that

there is adequate filtering on the bias lines.
