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.

Description
M/A-COM’s AM-140 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-140 is ideally suited for use where a high
intercept, high reliability amplifier is required.

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 3.5W must
be provided in use. The flange should be screwed down to the heat sink, which should be RF ground.
