GENERAL DESCRIPTION

The ADL8154 is a small form factor, low phase noise amplifier

designed for instrumentation, radar, and telecommunications appli-

cations. The phase noise from 2 GHz to 5 GHz is −172 dBc/Hz at 1

dB compression (P1dB) and 10 kHz offset.

The ADL8154 operates from a single positive supply (VCC); its bias

current (ICQ) is set by a resistor connected between the RBIAS pin

and the VCC1 and VCC2 pins. The RF input and RF output are

DC-coupled and matched to 50 Ω. A bias inductor is required on the

RF output.

The typical gain and noise figure are 16.5 dB and 3.5 dB , respec-

tively, from 2 GHz to 5 GHz. The typical output third-order intercept

(OIP3) and output second-order intercept (OIP2) are 34.5 dBm and

53 dBm, respectively, from 2 GHz to 5 GHz. The nominal supply

voltage is 5 V, and the supply current is 125 mA.

The ADL8154 is fabricated on gallium arsenide (GaAs), heterojunc-

tion bipolar transistor (HBT). The device is housed in a RoHS-com-

pliant, 2 mm × 2 mm, 8-lead LFCSP and is specified for operation

from −55°C to +125°C.
