摘要

报道了65 GHz钡铁氧体调谐gunn振荡器的初步结果，类似于yig -sweep。电子调谐是通过一个单晶钡铁氧体球体耦合到像线振荡器电路来完成的。铁氧体的高内部磁场大大减少了在毫米波频率下进行铁氧体磁共振所需的外部磁场。新的毫米波振荡器设计具有宽调谐范围和良好噪声性能的潜力。

A Millimeter-Wave Gunn-Oscillator, Tunable with a Barium-Ferrite Sphere

First results of a 65 GHz barium-ferrite tuned Gunn-oscillator are reported, similar to the YIG-sweepers. Electronic tuning is accomplished by a single crystal barium-ferrite sphere coupled to the image line oscillator circuit. The high internal field of the ferrite considerably reduces the external magnetic field required for ferrimagnetic resonance at mm-wave frequencies. The new mm-wave oscillator design has the potential for wide tuning ranges and good noise performance.
