Abstract
Low noise amplifiers (LNAs) with output limiting are provided herein. In certain implementations, a gallium nitride (GaN) LNA includes LNA amplification circuitry and an output limiter that is connected to an output of the LNA amplification circuitry and operable to limit an output power of the GaN LNA. By limiting the output signal power, a number of benefits are achieved, including protection of downstream circuitry receiving the GaN LNA's output signal. For example, such downstream circuitry can be fabricated using silicon or other fabrication technology associated with a lower signal power handling capability relative to that of the GaN LNA.
