Abstract

A 60-GHz frequency-stabilized small oscillator consisting of a Gunn diode, a circulator, and a matched termination is fabricated by using NRD guides. The emphasis in this paper is adaptability to a rectangular waveguide circuit. To this end, an NRD guide–waveguide transition is designed. In the 60-GHz NRD Gunn diode oscillators to date, Gunn diodes sealed in a package dedicated to the NRD guide have been placed on special order. With a view to cost reduction, a Gunn diode mount is conceived in which a general-purpose-type Gunn diode can be used. The oscillation output of the fabricated oscillator is 13 dBm and the phase noise at 300 kHz offset is −113 dBc/Hz. Further, the frequency variation due to ambient temperature change is −1.3 ppm/°C so that the fabricated millimeter-wave oscillator is highly stable, with medium power output and low noise. © 2007 Wiley Periodicals, Inc.

60 GHz下中功率、低相位噪声的矩形波导兼容NRD波导振荡器

利用NRD波导制作了一个由Gunn二极管、环行器和匹配端部组成的60 ghz小稳频振荡器。本文的重点是对矩形波导电路的适应性。为此，设计了一种NRD波导转换。在迄今为止的60 ghz NRD Gunn二极管振荡器中，密封在专用于NRD指南的封装中的Gunn二极管已被放置在特殊订单中。为了降低成本，我们设计了一个Gunn二极管支架，其中可以使用通用型Gunn二极管。制作的振荡器的振荡输出为13 dBm，在300 kHz偏移处的相位噪声为- 113 dBc/Hz。此外，由于环境温度变化引起的频率变化为- 1.3 ppm/°C，因此制造的毫米波振荡器具有高稳定性，中等功率输出和低噪声。©2007 Wiley期刊公司电子工程学报，2009,29 (3):326 - 326,2007;在线发表于Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002 / ecjb.20290
