Coupling mitigation for coextensive signal paths with resonant matching networks

Wireless circuitry comprising:

• a substrate;
• a first differential signal path on the substrate and having a first transformer;
• a second differential signal path on the substrate and having a second transformer, wherein the first transformer has a non-zero coupling constant with the second transformer;
• an amplifier disposed on the first differential signal path;
• and
• a crossover on the first differential signal path.

An integrated circuit comprising:

• a first signal line;
• a second signal line, the first signal line and the second signal line forming a first differential pair of signal lines;
• a first inductor that couples the first signal line to the second signal line;
• a third signal line;
• a fourth signal line, the third signal line and the fourth signal line forming a second differential pair of signal lines;
• a second inductor that couples the third signal line to the fourth signal line, the first inductor having a non-zero magnetic coupling constant with the second inductor;
• an amplifier disposed on the second differential pair of signal lines;
• and
• a crossover between the third signal line and the fourth signal line, the crossover being between the inductor and the amplifier.
