Research Of W-band Frequency Multiplier Components

With the rapid development of science and technology,weapon equipment and other civilian products require higher and higher frequencies.W-band technology not only plays an increasingly important role in military weapons,but also holds a significant market for civilian products.The W-band frequency source is the core component of the system or instrument that forms the band,but China has long been subject to the technical blockade of developed countries,led by the United States,for devices and related instruments in this band.This subject mainly develops a W-band frequency multiplication module,which is not only an in-depth exploration of the frequency multiplier,but also a beneficial exploration of the W-band frequency source.The W-band frequency doubling component adopts a frequency multiplication chain method.The pre-stage frequency multiplier uses an active chip twice frequency multiplication,and the subsequent-stage frequency multiplier uses a passive diode 3times frequency multiplication,and passes a total of 6 frequency multiplications.The Ku-band signal is multiplied to the W band.The W-band frequency doubling module developed in this paper has the characteristics of high frequency multiplier,low cost and wide frequency multiplier bandwidth.This paper describes in detail the design and development process of the W-band frequency multiplication module.First,according to the index requirements of the frequency multiplication module,the basic design scheme of the frequency multiplication module is proposed,and the simulation design of each module is performed through the electromagnetic simulation software ADS and HFSS.Due to the requirement of higher output frequency,the simulation design is more difficult,so the focus of this paper is on the simulation design of the post-frequency multiplier and W-band band-pass filter.The latter stage frequency multiplier uses two Schottky diodes in parallel to increase the power capacity,and uses a wide-band electromagnetic coupling structure and impedance matching to improve the simulation and test results.The W-band bandpass filter uses a novel finline structure with a waveguide embedded circuit substrate,which reduces the filter’s requirements for processing accuracy.Finally,each module was produced and debugged.After each module reached the preset technical specifications,the entire link was tested with the corresponding system.Finally completed the development of frequency multiplier components from the Ku band(15-16.7 GHz)to the W band(90-100 GHz).When the input signal power is-5dBm,the W-band frequency doubling component typically has output signal power greater than 0 dBm in the entire 90-100 GHz frequency band,and there are two point frequency signal powers exceeding +5 dBm.
