The ADL8107 is a GaAs, MMIC, pHEMT, low noise wideband

amplifier with integrated ac coupling capacitors and a bias inductor.

Figure 78 shows a simplified schematic.

The ADL8107 has ac-coupled, single-ended input and output ports

with impedances that are nominally equal to 50 Ω over the 6 GHz

to 18 GHz frequency range. No external matching components are

required. To adjust IDQ, connect an external resistor between the

RBIAS and VDD pins.
