“…Thus, the port-to-port isolation and the rejection to the even order spurious response of the mixer are improved [11]. The IF-signal can be extracted from the centre point of the U section.…”

A 26∼40 GHz millimeter-wave monolithic passive IQ mixer was designed by using Win's 0.15-µm GaAs pHEMT process. It utilizes a ring diode structure, and the performance can be improved effectively by a modified Marchand balun and U-type coupled lines. Through on-wafer measurement, the mixer shows a conversion loss of 6.6∼9 dB over a bandwidth of 26∼40 GHz, an IF bandwidth from DC to 6 GHz, an image rejection ratio of 21∼30 dB, an LO-RF isolation of above 24 dB, an LO-IF isolation of above 35 dB, and an RF-IF isolation of above 25 dB.

“…In many wireless communication systems, Baluns which provide balanced outputs from an unbalanced input are key components in balanced circuit topologies such as double balanced mixers, push-pull amplifiers, and frequency doublers [1][2][3]. Various balun configurations have been used for applications in monolithic microwave integrated circuits (MMICs) and millimeter-wave circuits [1][2][3][4][5][6][7][8][9].…”

This paper presents the design and analysis of general baluns of Marchand-type with a transmission line connected between two sections. A series of new expressions of Sparameters are derived for such type of Marchand balun. The relations between the length of interconnected transmission line and the imbalance of Marchand balun are discussed. By using analytical method, a millimeter-wave Marchand balun was designed and simulated by the full-wave electromagnetic software HFSS, and fabricated in 0.15 µm pHEMT GaAs process. The measurement results show that the balun achieves low insertion loss and good balance in the band of 24-40 GHz. The results are in good agreement with the simulated ones. The theoretical analysis is verified.

“…These desirable mixer properties are often exploited to realise high performance receivers with low intermodulation distortion [1][2][3][4][5][6][7][8][9][10]. These properties, however, are equally desirable in transmitter applications for upconverting signals with low spurious output.…”

“…It consists of an arrangement of four mixing elements with LO, RF and IF baluns. Schottky diodes have been the primary device employed for the mixing elements [1][2][3][4]. Due to their highly non-linear characteristics, they inherently exhibit poor intermodulation and spurious response properties.…”
