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-order

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 integration

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.
