第一幅图,讲得是泰哥搞出来的W-Band VCO,调谐范围在75GHz-85GHz;第二幅图,讲得是阿蛋搞出来的四倍频器,工作频率至少到40GHz吧,也就是说,输出频率至少到160GHz。这些都是实打实的测试数据,负责任地说,俺们组,不忽悠! 当然,除了这些玩意,俺们这次还有更好的东东,那是一个W-Band的PA MMIC。频段嘛,80GHz以...
A new type of circulators is presented which has been tested using circuits covering the frequency range from L- to W-band. This is, for the first time, a principle suitable for applications at 1.8 GHz as well as 77 GHz. At the lower frequencies ferrite drop-in circulators in microstrip...
A frequency-tunable yttrium iron garnet (YIG) oscillator provides sweep rates as high as 1.8 × 10 5 GHz/s, which corresponds to 6.3 kT/s in magnetic field-sweep units over a 44 MHz range. Two experimental domains were identified. In the first, linear frequency sweep rates were relatively...
In this article the theoretical and experimental performances of a Gunn harmonically synchronized frequency divider are presented. The results show that such a divider has a 96-32GHz division, with 15-mW output power over the operating band greater than 1400MHz at 10-mW input power level....
value of the W-band frequency during the frequency sweep. They could alternatively be expressed in terms of the complex value of the EPR signal and the resonator reflection coefficient. Since a rotating frame can be defined at Q-band, and also 1 GHz, absorption and dispersion can be detected...
A very broadband Q- to W-band MIC frequency doubler with a 28-Ghz bandwidth, employing a unique planar balanced circuit configuration, has been developed using two beam-lead Schottky barrier diodes as varistors. The doubler exhibits output power of 7 + or - 1 dBm and conversion loss of 13...
In millimeter-wave, phase-locked oscillators are often used because the frequency drift of oscillators is very large. However, they are very complex. In this paper, a W-band frequency tracing transceiver system is presented and tested, which is used for digital communication. Although the communic...

The frequency is: f=1T=14.17×10−10s=2.40×109Hz This is the 2.4 GHz wi-fi band. Finally, TV channels in the U.S. are broadcast at a range of frequencies, but some in the band III frequency range have around f = 200 MHz = 200 × 106Hz. What is the period of this...
