The ADL8122 is a wideband LNA that operates from 10 kHz to 10

GHz. A simplified block diagram is shown in Figure 91.

The ADL8122 has DC-coupled, single-ended input and output

ports with impedance that is nominally equal to 50 Ω over the

specified frequency range. No external matching components are

required; other than, AC input and output coupling capacitors and

a bias inductor. To adjust IDQ, connect an external resistor between

the RBIAS and VDDx pins. The VBIAS output voltage provides

a DC bias voltage; it connects to RFIN through a ferrite bead.

The RFOUT/VDD1 pin provides the drain current. Additional drain

biasing is applied through the VDD2 pin.
