“…The four six-port outputs are connected to the power detectors to recover the low IF or the baseband signals. The HSCH-9161 mm-wave zero bias GaAs Schottky diode of Agilent Technologies is chosen for power detection, due to its broadband and high-speed properties [22]- [23].…”

The realization and analysis of an implemented V-band six-port demodulator, operating over 60 GHz band, are presented in this paper. The performance of the design in real-time high-data-rate wireless data transmission is strongly proved using different modulated signals. The valid high data-rate demodulation results achieved over a 7 GHz band (from 57 to 64 GHz), provide a confirmation that this six-port interferometer receiver is an attractive proposition for homodyne or heterodyne transceivers designed for high-speed short-range wireless communication systems, such as future wireless small cell backhaul for 5G. The performance of the proposed direct conversion receiver is characterized in terms of the bit error rate (BER) and error vector magnitude (EVM) for various M-PSK/M-QAM demodulated signals. To verify the resulting data, the relation between the error vector magnitude and the bit error rate is also analyzed. Theoretical results are matched to measured values and validate that the EVM and BER are appropriate metrics for mm-wave channels limited by additive white Gaussian noise. In the last section, the proposed six-port interferometer is introduced for precise estimation of carrier frequency offset (CFO) and Doppler shift in V-band wireless systems. The final results, which include various modulation configurations at mega or Giga symbol rates generated by the implemented transmitter, are supported by laboratory measurements.INDEX TERMS Bit error rate, carrier frequency offset, direct conversion receiver, fifth-generation (5G) systems, error vector magnitude, multiport interferometer, six-port junction.

A high voltage responsivity detector in G‐band is designed in this paper. Different grounding models for the terahertz detector are analyzed and designed. Gold wire grounding design is superior to traditional grounding designs, which reduce the influence caused by the doping concentration, position and thickness error of conductive adhesive. Detectors are based on the Virginia Diodes Inc G‐band zero‐bias Schottky diode with low zero‐bias junction capacitance. The voltage responsivity test result of the gold wire grounding detector is about 1800 mV/mW in 210–220 GHz. The development of the detector provides the device basis for the realization of a terahertz focal plane imaging system.

“…The matching network is represented by the DC block capacitor ( C b ) with the stubs (l1, l2, l3, l4). This network is important to ensure that the maximum RF power is absorbed by the detector, meanwhile avoiding standing waves 10 . In order to design the matching network, the complete detector circuit is simulated in Cadence virtuoso for two detectors (L1N1 and L2N5), where the diodes are represented by their extracted small signal models.…”

This paper presents the design and characterization of two tunable power detectors, based on PN diodes, integrated in SiGe 55-nm BiCMOS technology from ST-Microelectronics. The working frequency band of the circuits is (35-50) GHz dedicated for 5G applications. The detector parameters are adjusted by controlling the biasing current, this characteristic makes them suitable to be utilized in different 5G applications. Two different diode sizes are used (L1N1, L2N5) in order to compare their performances. For three values of biasing current, the extracted voltage sensitivity values are between (700-1400) V/W for L1N1 and (500-1150) V/W for L2N5 showing the agreement with the simulation. Comparing to recent works, our designs exhibit very low power consumption (down to 60 nW) with relatively high sensitivity values. A targeted sensitivity value can be obtained with lower power consumption using larger diode size.
