GENERAL DESCRIPTION

The ADL8120 is an ultra-wideband low noise amplifier (LNA) that

operates from 30 kHz to 20 GHz. Typical gain and noise figure are

14 dB and 1.9 dB, respectively, from 30 kHz to 14 GHz. Output

power for 1 dB compression (OP1dB), output third-order intercept

(OIP3), and output second-order intercept (OIP2) are

16 dBm, 29.5 dBm and 33 dBm, respectively, from 30 kHz to

14 GHz. The nominal quiescent current (IDQ), which can be adjusted,

is 55 mA from a 3.3 V supply voltage (VDD). The internally

matched, DC-coupled RF input and output pins require external

AC coupling capacitors along with a bias inductor on RFOUT.

In addition, the RF input is biased through an external inductor

connected between the VBIAS pin and the RFIN pin.
