Broadband LNA structure using offset active coupled segments

A broadband low noise amplifier (LNA) structure comprising:

• an input port;
• an output port;
• a main LNA;
• a first offset LNA parallel with the main LNA;
• an input splitter configured to split a radio frequency (RF) input signal received from the input port into a first RF input signal and a second RF input signal, which are fed to the main LNA and the first offset LNA, respectively, wherein:
• the first RF input signal and the second RF input signal have a phase difference;
• the main LNA is configured to provide a first RF output signal based on the first RF input signal;
• and
• the first offset LNA is configured to provide a second RF output signal based on the second RF input signal, wherein the first RF output signal and the second RF output signal have a phase difference due to the phase difference between the first RF input signal and the second RF input signal;
• and
• an output combiner configured to re-align the first RF output signal and the second RF output signal by decreasing the phase difference between the first RF output signal and the second RF output signal, and configured to combine the first and second RF output signals to provide a combined RF output signal to the output port, wherein:
• a main signal path, which extends from the input port, through the input splitter, through the main LNA, through the output combiner, and to the output port, includes a main total inductance;
• and
• a first offset signal path, which extends from the input port, through the input splitter, through the first offset LNA, through the output combiner, and to the output port, includes a first offset total inductance, wherein the main total inductance and the first offset total inductance have different values.
