Low noise amplifier with combined input matching, balun, and transmit/receive switch

An integrated circuit comprising:

• a coupled inductor configured to receive a single-ended input signal, to perform single-ended to differential conversion, and to generate a differential input signal at least in part by conductively coupling the single-ended input signal to an input signal of the differential input signal;
• and
• a low noise amplifier (LNA) coupled to the coupled inductor and configured to receive the differential input signal and to generate a differential output signal.

A method comprising:

• converting a single-ended input signal to a differential input signal at least in part by conductively coupling the single-ended input signal to an input signal of the differential input signal with a coupled inductor implemented on an integrated circuit;
• and
• amplifying the differential input signal with a low noise amplifier (LNA) implemented on the integrated circuit to obtain a differential output signal.

An apparatus comprising:
