description: This work is devoted to the research and design of an analog multiplier on differential stages for the microwave range. Various analog multipliers, their circuits, applications and functionality were considered. Analog multipliers can be used for:squaring the voltage to double the frequency, divide the voltage, extract the square root, phase detection, rectification.The topic of transistors based on silicon-germanium technology was raised. It turned out that a transistor of this type is most suitable for our chosen circuit. Firstly, its increased band gap can reach tens of gigahertz. Secondly, the gain of such transistors is several times higher than that of silicon. In the process, an analog multiplier circuit was built on differential stages, which produces a squaring function. The range of input signals with a relative error not exceeding 10% is from -0.45 V to 0.45 V.
