GENERAL DESCRIPTION

The ADL8140 is a low noise amplifier (LNA) that operates from 10

GHz to 18 GHz.

Typical gain and noise figure are 27.5 dB and 1 dB, respectively,

from 12 GHz to 15 GHz. Output power for 1 dB compression

(OP1dB) and output third-order intercept (OIP3), are 8 dBm and 23

dBm, respectively, from 12 GHz to 15 GHz. The nominal quiescent

current (IDQ), which can be adjusted, is 35 mA from a 1.5 V supply

voltage (VDD). The ADL8140 also features inputs/outputs that are

AC-coupled and internally matched to 50 Ω.

The ADL8140 is housed in a RoHS-compliant, 2 mm × 2 mm,

8-lead lead frame chip scale package [LFCSP] and is specified for

operation from −55°C to +125°C.
