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.
APPLICATIONS
► Electronic test and measurement equipment
► Electronic warfare
► Wireless receivers
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.
