FMA246
HIGH-GAIN X-BAND MMIC
• DESCRIPTION AND APPLICATIONS
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 +85°C), and conditionally stable if the
input port is open-circuited.
