GENERAL DESCRIPTION

The ADL8112 is a low noise amplifier (LNA) with bypass switches

that provides broadband operation from 10 MHz to 26.5 GHz. The

ADL8112 provides a low noise figure of 4 dB and an output third-or-

der intercept point (OIP3) of 22.5 dBm. The ADL8112 provides a

gain of 13.5 dB that is stable over frequency, temperature, power

supply, and from device to device.

The integration of an amplifier and two single-pole, four-throw

(SP4T) reflective switches allow multiple paths through the device.

The addition of switches also offers a high third order input intercept

(IIP3) path when large input signals are present. With the integra-

tion of power supply decoupling capacitors, minimal external power

supply decoupling is required.

The ADL8112 is fully specified for operation across a temperature

range of −40°C to +85°C. The ADL8112 is offered in a 6 mm x 6

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