TransferJet™ is an emerging high-speed close-proximity wireless communication standard, which enables a data transfer up to 522Mbps within a few centimeters range. We present a fully integrated TransferJet SoC with a 4.48-GHz operating frequency and a 560-MHz signal bandwidth using a 65nm CMOS technology. Baseband filtering techniques for a transmitter (TX) and a receiver (RX) are proposed in order to handle the ultra-wide bandwidth with low power consumption and small area. A programmable power attenuator (PAT) for precise output power is also proposed in this paper. The SoC achieves energy efficiencies of 0.19nJ/bit and 0.43nJ/bit for the TX and the RX, respectively. The RX sensitivity of -70dBm for 522Mbps data rate and the TX error vector magnitude (EVM) of -31dB are achieved.
