“…Additionally, the challenge for a ring DBM design is IF signal extraction. Previous ring DBM designs require an additional extraction circuit for the IF port [5][6][7] to enhance RFto-IF isolation. These methods may still cause layout complications, making the integration of the mixer in a low-cost and compact system more difficult.…”

Abstract-To meet the requirements for broadband operation, high port-to-port isolation, and miniature chip area, a doubly balanced monolithic microwave ring mixer with an advanced IF extraction fabricated using 0.15 µm GaAs pHEMT process is presented. A miniature Marchand-like spiral balun with low-pass filter is used to extract IF signals and maintain balun performance simultaneously. The low-pass filter can filter out both the RF and LO signals. This miniaturized mixer design can mitigate layout complexity, improve port-to-port isolations suitable for ultra-broadband Ku-, K-, and Kaband applications. Subsequently, the LO/RF-to-IF isolations are greater than 43.2 and 32 dB from 11 to 40 GHz, respectively. The LO-to-RF isolation is between 26.9 and 50.7 dB within the same swept range. The conversion loss is 7.2-12.4 dB within the operating bandwidth.

“…The mixer is one of the key circuits in millimeter wave front-end system, which is responsible for converting millimeter wave signal to intermediate frequency (IF) signal. With good conversion gain, compact size, and superior spur rejection, the fundamental mixer is widely used in modern CMOS radio frequency integration circuits, and further extended to 5G transceiver front-end in millimeter wave band [2,3]. In comparison to the fundamental mixer, the sub-harmonic mixer can decrease the LO frequency by half or several times, thus reduce the requirements of high-performance signal source, especially when the circuit operating frequency is greater than 100 GHz.…”

A Compact Broadband Monolithic Sub-Harmonic Mixer Using Multi-Line Coupler

A compact broadband monolithic sub-harmonic mixer is presented in a 70 nm GaAs Technology for millimeter wave wireless communication application. The proposed mixer adopts a novel multi-line coupler structure; where the two-sided coupling energy of radio frequency (RF) and local oscillation (LO) signals are both collected and efficiently feed to anti-parallel diode pair (APDP) topology; resulting in broadband performance and compact chip size. As a comparison in the same circuit configuration; the five-line coupler can expand the bandwidth of the existing three-line coupler by 85% and reduce the area by 39.5% when the central frequency is 127 GHz. The measured conversion gain is −16.2 dB to −19.7 dB in a wide operation frequency band of 110–170 GHz. The whole chip size is 0.47 × 0.66 mm2 including test pads. The proposed mixer exhibits good figure-of-merits for D-band down-converter applications

“…Balanced topology is another approach, which is widely adopted when designing a mixer with a compact size and perfect port‐to‐port isolations. Mixers using balanced topology are usually composed of a mixer‐core, which can be a diode‐cell or a FET‐cell, and several balance‐to‐unbalance circuits, namely, baluns. Usually, the performance of the diode or the FET is determined once the process is determined.…”

In this article, a 7‐GHz to 40‐GHz ultra‐wideband passive double‐balanced mixer MMIC using compact wideband Marchand balun (CWMB) is presented. The CWMB is analyzed and designed by introducing a novel optimal impedance deviation coefficient. A trade‐off between the needed bandwidth and the acceptable insertion loss in an ultra‐wideband passive‐doubly‐balanced mixer design can be made through introducing the optimal impedance deviation coefficient. Finally, to verify the proposed methodology, a compact wideband passive double‐balanced mixer monolithic microwave integrated circuit (MMIC) was designed and fabricated using a standard gallium arsenide (GaAs) pHEMT technology according to the process characteristics. Experimental results show that an ultra‐wideband mixer MMIC is realized from 7 GHz to 40 GHz (140% fractional bandwidth) with a measured conversion loss between 9.5 dB~12.5 dB (in‐band fluctuation less than 3 dB) and a LO‐to‐RF isolation larger than 34 dB. The measurement results are in good agreement with the simulation results.
