“…The frequency band 71 GHz to 76 GHz is allocated for several applications by the International Telecommunication Union (ITU) and The European Telecommunication Standards Institute (ETSI) [9]. A variety of microwave filters with different characteristics of low insertion loss, high quality factor Q, and good frequency selectivity for E-band applications have been proposed [2,[10][11][12][13][14][15][16][17][18]. These studies have been implemented based on the direct coupling phenomena [1,19].…”

A new design of bandpass waveguide filter with Chebyshev response which operates in the E-band for downlink channel [71 GHz-76 GHz] at 73.5 GHz center frequency. The new design used a complementary split ring resonators (CSRRs) upper and lower rings that are placed on the same transverse plane. A simple model of lumped elements circuit (RLC) model is shown. The model of the proposed bandpass waveguide filter is synthesized and designed by using EM full-wave simulator CST. By selecting proper physical dimensions of CSRR design, a shortened physical length, a flat and lossless passband with better return loss over the conventional waveguide filter are obtained. As a result, the proposed filter is compared with the conventional bandpass waveguide filter coupled by inductive H-plane irises at the same resonant frequency 73.5 GHz. The proposed filter reduces the overall physical length by 37.5% and enhances the return loss up to 6.7%.

“…Especially in the case of absence of terahertz low noise amplifier, the impact of the mixer on the system is more significant due to its role as the first stage of the receiver system [5], [6]. Besides, because of the difficulty in fabricating terahertz oscillator sources, harmonic mixers that can reduce local oscillation frequency are widely used to make the LO power requirements more readily complied with [7]- [12]. At present, the researches of terahertz harmonic mixers…”

“…However, this also limits the application of some special structures in harmonic mixing circuits, such as balanced structure, fin line, etc. But, since the fundamental diode connection mode of odd harmonic mixing circuit is different from that of even harmonic mixing circuit, [7], [14]- [18], these special structures can be used in odd harmonic mixing circuit to obtain better performance, and smaller size, higher isolation. The research of odd harmonic mixer not only enriches the study of terahertz harmonic mixer but also provides a new construction method for terahertz communication and radar systems.…”

This paper proposes a novel 220-GHz third-harmonic mixer, which using a waveguide-fincoplanar waveguide-microstrip line hybrid transmission line as the carrier circuit, based on the balanced structure and the co-directional diode pair. The hybrid transmission line is designed to allow the mixing signals to be input in the correct direction in order to achieve the third-harmonic mixing. Then, high isolation between the radio-frequency (RF) port and the local oscillator (LO) port is performed through the mode orthogonality of the balanced structure. The metal slots on the fin line are used as the matching network for the RF signal to enable the RF signal into the diode pair with low loss. The experimental test results show that the conversion loss of the third-harmonic mixer is better than 18.5 dB in the range of 210-230 GHz and has a tiny fluctuation in the broad range of intermediate frequency (IF).INDEX TERMS Terahertz, hybrid transmission line, odd harmonics mixer, balanced structure.

“…Compared with even harmonic mixer with a pair of antiparallel diodes, odd harmonic mixer has a better performance of radio frequency (RF)-to-LO isolation due to its balanced configuration. Odd harmonic waveguide mixers have been reported in the past years, and demonstrated having good performance [5,6,7]. However, these mixers are unsuitable for integrating with other planar circuits for their 3D structures.…”

A planar millimeter-wave third-harmonic mixer with low conversion loss is proposed. The mixing circuit consists of a substrate-integrated waveguide (SIW) balun, a pair of diodes, a diplexer and microstrip matching circuit. The mixer is ideal for use as down-converter and up-converter. For a fixed intermediate frequency (IF) of 2 GHz, the mixer has an up-conversion loss of 14.5-15.6 dB and a down-conversion loss of 14-15.6 dB over the radio frequency (RF) band of 38-47 GHz. For a fixed local oscillation (LO) frequency of 13 GHz, the mixer has a conversion loss of 10-15.8 dB over the IF frequency band of DC-6.4 GHz. The proposed mixer offers an effective and low-cost solution for millimeter-wave applications.
