10MHz to 12GHz Low Noise Amplifier with 10MHz to 14GHz Bypass Switches

The ADL8113 is a low noise amplifier (LNA) with bypass switches that provides broadband operation from 10MHz to 12GHz. The ADL8113 provides a low noise figure of 3.8dB and an output third-order intercept point (OIP3) of 35.5dBm from 200MHz to 6GHz. The ADL8113 provides a small signal gain of 14.0dB that is stable over frequency, temperature, power supply, and from device to device.

The integration of an amplifier and two SP4T reflective switches allows multiple paths through the device. The addition of switches also offers a high input third-order 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 ADL8113 is fully specified for operation across a temperature range of −40°C to +85°C. The ADL8113 is available in a 6mm × 6mm, 28-terminal land grid array (LGA) package.
