GENERAL DESCRIPTION

The ADL8111 is a low noise amplifier (LNA) with a nonreflective

bypass switch that provides broadband operation from 10 MHz to

8000 MHz. The ADL8111 provides a low noise figure of 2.8 dB with

a high output third-order intercept (OIP3) of 34 dBm simultaneously,

which delivers a high dynamic range. The ADL8111 provides a gain

of 12.5 dB that is stable over frequency, temperature, power supply,

and from device to device.

The integration of an amplifier and two single-pole, quad-

throw (SP4T) nonreflective switches allows multiple gain and linear-

ity values. The addition of switches also offers high input intercept

performance and prevents distortion on the high signal level appli-

cations.

The ADL8111 has a high electrostatic discharge (ESD) rating of

±750 V (Class 1B) and is fully specified for operation across a wide

temperature range of −40°C to +85°C. The ADL8111 is offered in a

6 mm × 6 mm, 28-terminal land grid array (LGA) package.
