提出了一种基于相位控制的push-push四倍频器,在121-137GHz频段实现9%的功率效率,可用于高频信号源生成。解决了高数据率短距离通信和成像系统中对纯净稳定信号源的需求。
Institute of Microelectronics, Singapore, Singapore 3 MicroArray Technologies, Chengdu, China 1 2 High-data-rate short-range communication and image systems beyond 100GHz impose crucial requirements on signal sources, demanding superior purity and stability. Using frequency multipliers with high efficiency and multiplication factor to generate the Nth harmonic signal that is phase-locked by a PLL at the fundamental frequency provides an alternative solution. The desired signal in an active frequency multiplier can be generated using Class B/C amplifiers, where a half-wave signal containing all harmonics is first created and then filtered to remove the undesired harmonic components [1]. Another approach is to apply the same signal to both the IF and RF ports of a mixer to construct a doubler followed by cascading to form the quadrupler [3]. The linear superposition (LS) technique that superimposes four phase-shifted half-waves of 0°, 90°, 180°, and
