The FMA246 is a 3-stage, reactively matched pHEMT high-gain MMIC amplifier designed for use over the 8 to 14 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. Typical applications include general (low noise) gain block utilizations in X-band. The amplifier is unconditionally stable over all load states (-45 to +85C), and conditionally stable if the input port is open-circuited.
