BALANCED MIXER BASED ON A MICROSTRIP LINE

Ján Labun, Viktor Képeši

Abstract


The paper describes the design and implementation of a balanced mixer based on microstrip lines in the WiFi frequency range (2.4 GHz) for the purpose of evaluating the frequency ratio of the two frequencies near the signal. The introduction sets out the issues of microstrip lines and their design solutions. The next chapter analyses the coupler based on microstrip lines. The core of the paper is focused on the description of the balanced mixer and its involvement in the radio altimeter RV-5, including the production of mixers of this type and the results of laboratory measurements performed on these mixers. The conclusion shows the measurement results of the phase distribution ratios on the realised horn aperture.

Keywords
