为雷达应用的大功率毫米波发射机的需要已为固态沅创造了很大的销路。碰壁(?)崩渡越时间器件近来的发展已产生13~W峰值输出功率的振荡。在W-频带的直流到射频的转换效率为8％,但是基本的热和阻抗的限制已阻碍了这些器件达到系统应用所需要的更高的功率电平。为达到需要的大功率电平,已在W-频带~1提出功率组合技术,也就是在一个有效地组合功率的电路中接入几个双二极管。 The need for high-power millimeter-wave transmitters for radar applications has created a huge market for solid-state devices. The recent development of run-in devices (tB) has resulted in oscillations of 13 ~ W peak output power. The conversion efficiency of DC to RF in the W-band is 8%, but the basic thermal and impedance constraints have prevented these devices from reaching the higher power levels needed for system applications. In order to achieve the required high power level, a power combining technique has been proposed in the W-band ~ 1, that is, several double diodes are inserted in an effectively combined power circuit.
