“…Therefore, research on wideband high performance balun is meaningful for RF frond-ends. Over the past few years, much effort has been focused on this area [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

“…In order to reduce the circuit dimension, baluns based on low-temperature co-fired ceramic (LTCC) technology and COMS technologies were presented in [1][2][3], respectively, yet the multilayer process increases the complexity and the cost of the circuits. By combining the lumped element and microstrip line, lumped-element baluns were introduced with compact size in [4] and [5], while they could not realize wide bandwidth due to inherent characteristic of lumped elements.…”

A new compact 30 : 1 bandwidth ratio balun and its application to balanced antennas are presented in this paper. To realize the balun-type function, two different types of wideband transition structures are adopted for unbalanced and balanced outputs of the balun. Further, a Vivaldi antenna integrated with the proposed balun is designed and fabricated to validate the feasibility of the new approach. Results indicated that the proposed balun can operate from 0.2 GHz to 6 GHz (a bandwidth ratio of 30 : 1). And it exhibits a good balanced performance within 0.5 dB magnitude imbalance and less than 6 degree phase imbalance between the two balanced outputs. In addition, the antenna can operate from 0.9 GHz to 6 GHz with good unidirectional radiation patterns.

A new ultra-wideband balun and its application for balanced antenna are presented in this paper. To realize the balun-type function, two different types of microstrip to slotline transition forms are adopted for the unbalanced and balanced outputs of the balun. Further, an ultra-wideband balun and its integration with a Vivaldi antenna are designed and fabricated to validate the feasibility of the new approach. Results indicated that the proposed balun and the antenna can operate from 3.6 to 10.7 GHz. For the proposed new balun, it exhibits a good balanced performance of within 0.5 dB magnitude imbalance and less than 6°phase imbalance between the two balanced outputs. Meanwhile, the antenna reveals good unidirectional radiation patterns.

“…The K-band (18-26.5 GHz), which includes automotive radar applications (24 and 22-29 GHz), ISM band (24 GHz), and point-to-point communications (18-25 GHz), is one of the most important frequency bands in modern wireless communication system. [1][2][3] Due to its low cost and high yield, CMOS process has already been the dominant technology in microelectronics industry. However, because of the low breakdown voltage, low transconductance(gm), and high substrate loss, the sufficient gain and output power is very difficult to achieve in high operation frequency.…”

A 18-24 GHz broadband power amplifier (PA) by 0.18-μm CMOS technology is presented in this article. The low loss microstrip line matching technique is used to reduce transmission losses and achieve higher gain, PAE, and enough output power. An improved gain-boosting technique is also included in the PA architecture to improve high-frequency gain and gain flatness. The measurement results show that small-signal gain is large than 18.5 dB from 18 to 24 GHz, while the gain variation is less than 1.5 dB. The maximum PAE is about 18%, and the output P 1dB is 13.1 and 15 dBm P sat .
