A 220 GHz frequency doubler based on plannar Schottky diodes
摘要
介绍了一个基于平面肖特基二极管的220?GHz倍频器。该倍频器工作在室温下,结构简单。为了实现倍频,将一个具有4个反向串联肖特基结的变容二极管安置在石英基片上,直流偏置通过一个石英微带构成的低通滤波器加到二极管上。所有的石英电路基片都用导电胶粘接在波导腔体上,波导腔体是E面剖分的,表面镀金。220?GHz倍频器的测试结果表明,在选择合适的偏置电阻时,该倍频器具有15?mW的输出功率和5%的效率。在213~230?GHz频段,二倍频器的输出功率均在10?mW以上,且带内的功率波动非常小。
Abstract
The development of a 220?GHz frequency doubler based on GaAs plannar Schottky diodes is described. The doubler works at room temperature, and its structure is very simple. A plannar Schottky varactor flip chip with four anodes arranged in anti-series is mounted onto a quartz based microstrip circuit to realize frequency multiplication. DC bias is put on the varactor through a low-pass filter circuit which is also constructed on a quartz microstrip. All the quartz circuits are glued into the waveguide block with conductive adhesive. The block is split in the E-plane and its surface is gold plated. Test data for the 220?GHz doubler show 15?mW output power with 5% efficiency when appropriate external bias resistor is selected. Over the 213-230?GHz,the output power of the doubler is above 10?mW,and the power fluctuation in this band is very small.
