ADL8111: Low Noise Amplifier

The ADL8111 is a low noise amplifier (LNA) with a non-reflective 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) non-reflective 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.
