Patent ID: 8554136

Claim:
An electronic product, comprising: a first substrate with a first conduction path disposed thereon; a second substrate with a second conduction path disposed thereon; a first near-field transmitter disposed on the first substrate and connected to the first conduction path, the first near-field transmitter operable to transmit a first carrier signal at a first transmit carrier frequency; and a first near-field receiver disposed on the second substrate and connected to the second conduction path, the first near-field receiver operable to near-field couple with the first near-field transmitter at the first transmit carrier frequency; wherein the first substrate and the second substrate are spaced apart relative to each other such that the first near-field transmitter and the first near-field receiver are disposed within a near-field coupling distance of each other at the first transmitter carrier frequency, wherein the first transmitter carrier frequency is in the extremely high frequency (EHF) range, wherein the first near-field transmitter is operable to translate a data signal from the first conduction path to a modulated carrier and the first near-field receiver is operable to translate the modulated carrier to a baseband signal on the second conduction path; and wherein the first conduction path comprises at least one pair of conductors configured to communicate at least one differential signal.
