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
metal flatpack the thermal rise 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 important that potential
ground loops be avoided, and that there is adequate filtering on
the bias lines.

3. All specifications apply when operated at +15 VDC, with 50 ohms source and load impedance.
4. Heat Sinking: Operation at case temperature above 95°C is not recommended. Heat sinking adequate to dissipate 2.7W must be provided in use.
The flange should be screwed down to the heat sink, which should be RF ground.
