GENERAL DESCRIPTION

The ADL8143 is a low noise amplifier (LNA) that operates from 8

GHz to 14 GHz. The typical gain, noise figure, output power for 1

dB compression (OP1dB), and output third-order intercept (OIP3)

are 28.5 dB, 1 dB, 7.5 dBm, and 19.5 dBm, respectively, from 8

GHz to 10 GHz. The nominal quiescent current (IDQ), which can be

adjusted, is 35 mA from a 1.5 V supply voltage (VDD). The ADL8143

also features inputs and outputs that are AC-coupled and internally

matched to 50 Ω.
