“…The presented synchronous demodulator achieves a very high data rate, exceeding those presented in [9] and [15]. Furthermore, based on the measurements with BPSK signals in [10], the presented demodulator can potentially demodulate up to a data rate of 10 Gb/s, and such a high data rate is demonstrated only in [14] and [5].…”

“…In [14], the high data rate is achieved through differential demodulation, which requires the received signal to be delayed by an exact symbol duration. This needs to be precisely controlled, and even a reference signal would be required, because a constant clock frequency at the transmitter cannot be guaranteed.…”

This paper describes Monolithic microwave integrated circuits (MMICs) and MMIC modules for 120 GHz 10-Gbps or more wireless data communications using ASK and QPSK modulation schemes. Record transmission distance of 5.8 km was established using ASK architecture MMICs at a data rate of 10-Gbps and a carrier frequency of 125 GHz. QPSK modulator and demodulator show that they performs full function in back-to-back test at a carrier frequency of 128 GHz at 10-Gbps. Furthermore, the QPSK chips was improved and integrated with low noise amplifier or power amplifier. In result, this QPSK transceiver chipset showed 22.2-Gbps error-free transmission at an output power of 7 dBm and received power -35 dBm in back-toback measurement.-125 GHz, MMIC, ASK, QPSK, millimterwave.

“…Over the past few years, THz wireless communication using electro-photonic technologies has seen impressive progress [4,5], but to adopt this approach will increase the system size because of the requirement for extra optical components. Recently, utilizing all-electronic technologies to fulfill THz wireless transmission attracts significant attention owing to the potential of system-on-chip integration [6,7,8,9,10,11]. In this regard, the existing primary technological bottleneck is the lack of enabling high-performance and cost-effective electronic devices.…”

In this paper, an all-electronic outdoor wireless communication system based on a Schottky-diode transceiver at 220 GHz is reported. The transceiver is implemented by the use of in-house designed 220 GHz lownoise Schottky diode-based subharmonic mixers (SHMs), which simplifies the system setup and demonstrates the feasibility of Schottky technology for terahertz (THz) communication. The system setup, performance of critical components and link budget calculation are presented. The wireless link quality is evaluated in terms of the error vector magnitude (EVM). 3.52 Gbit/s real-time three-dimension (3D) glass-free video transmission is achieved over an outdoor distance of 200 m by the use of quadrature phase shift keying (QPSK) modulation.
