Apple patents circuit trick to pack radio parts closer together
Apple has been granted a patent for a specific layout of electronic circuits used in wireless devices. The design places two signal paths side-by-side and uses a 'crossover' to flip the electrical polarity of one path. This technique reduces unwanted interference between the paths, allowing them to be packed tightly together on a chip.
In the filing’s own words
An electronic device may be provided with wireless circuitry that includes a transceiver. The transceiver may include a first signal path and a second signal path extending parallel to the first signal path. The first signal path may include a first chain of gain stages and a first inductive matching network. The second signal path may include a second chain of gain stages and a second inductive matching network. The first inductive matching network may be magnetically coupled to the second inductive matching network. The first and/or second signal path may include one or more crossovers that invert a polarity of the signals on the signal paths. The crossovers may help to mitigate the effects of the magnetic coupling between the first and second signal paths while allowing for minimal spatial separation between the signal paths.
What exactly they claim (claim 1)
1. An integrated circuit comprising: a differential signal path; an amplifier disposed on the differential signal path; and a transformer disposed on the differential signal path, wherein the differential signal path has a crossover between the amplifier and the transformer.
