The ADL8154 is a wideband low phase noise amplifier that oper-

ates from 10 MHz to 6 GHz. A simplified block diagram is shown in

Figure 80.

The ADL8154 has DC-coupled, single-ended input and output ports

with impedances that are 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 ICQ, connect an external resistor between the

RBIAS and VCC1 and VCC2 pins. The VBIAS output voltage

provides a DC bias voltage; it connects to RFIN through a ferrite

bead. The RFOUT/VCC1 pin provides the ICC. Additional collector

biasing is applied through the VCC2 pin.
