Application: Full-duplex contactless connectors (Patent ID: US20240204819A1)
The patent filed by NXP Semiconductors NV describes a contactless connector system that includes an antenna system and a wireless transceiver capable of transmitting and receiving signals simultaneously. The wireless transceiver consists of a transformer, wide-band phase shifter, and combiner to cancel self-interference in the received signal. The wide-band phase shifter includes a wide-band variable-delay line controlled by a first control signal, and a variable gain element controlled by a second control signal, both set through a calibration process.
Furthermore, the contactless connector system is designed for radio-frequency wireless communications in the millimeter-wave band, achieving data rates of at least 1 gigabit per second over distances not exceeding 50 millimeters. The system utilizes a hybrid transformer with a primary coil connected to the antenna system and a secondary coil connected to the combiner. The output of the combiner is processed through a mixer for frequency-shifting and a demodulator for generating received data. The method of implementing a contactless connection involves removing artifacts from the transmission signal through a self-interference-rejection/cancellation process using the transformer and wide-band phase shifter, achieving data rates of at least 2 gigabits per second over distances not exceeding 50 millimeters. Calibration processes are employed to determine the delay and gain settings for optimal signal reception.
