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.
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
±±50 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.
The integration of an amplifier and two single-pole, quad-
throw (SP4T) nonreflective switches allows multiple gain and
