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

linearity values. The addition of switches also offers high input

intercept performance and prevents distortion on the high

signal level applications.

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.
