Description
M/A-COM鈥檚 AM-177 is a feedback amplifier with high
intercept and compression points. This amplifier is
packaged in a TO-8 package. 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-177 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 95擄C is not recommended. Heat sinking adequate to dissipate 1.75W must
be provided in use.
