ESCRIPTION
:
The FMA246 is a 3-stage, reactively matched
pHEMT high-gain MMIC amplifier designed for
use over the 8 to 14 GHz bandwidth. The
supply voltage can be varied from +3V to +6V
if needed. Operating current can be adjusted
using the source resistor ladders located along
the bottom edge, by bonding a particular pad
to ground. The amplifier is unconditionally
stable over all load states (-45 to +85°C), and
conditionally stable if the input port is open-
circuited.

= 22°C; Continuous operation at IDSS is not recommended
2. 60%IDSS is achieved by bonding pads "D", "G", and "K" (shown on page 2) to ground to drive the 1st,
2nd and 3rd stage amplifiers at 50%IDSS, 50%IDSS, and 75%IDSS respectively.
