DESCRIPTION AND APPLICATIONS
The FMA411 is a 2-stage, reactively matched pHEMT low-noise MMIC amplifier designed for use
over the 8.5 to 14.0 GHz bandwidth. The amplifier requires a single +6V supply and one off-chip
component for supply de-coupling; the supply voltage can be varied from +3V to +6V if needed.
Both the input and output ports are DC de-coupled. Grounding of the amplifier is provided by plated
thru-vias to the bottom of the die, no additional ground is required. Operating current can be
adjusted using the Source resistor ladders located along the bottom edge, by bonding a particular pad
to ground, in order to optimize noise or power performance.
Typical applications include low-noise front end amplifiers, and general gain block utilizations in X-
band. The amplifier is unconditionally stable over all load states (-45 to +85擄C), and conditionally
stable if the input port is open-circuited.
