In the modern world interference logic gates (ILG) are an integral part of computers in the modern world. One of the most important tasks of developers of new computing technology is to reduce the duration of logical operations. This ensures the perfomance of various computing systems used in large objects modeling with a large number of details in various industries and in processing a large amount of information. A possible way to solve this problem is to use ILGs based on the element base of the optical wavelength range. These models microwave ILG are being developed for implement the functions of ILG based on a microstrip line in the ultra-high frequency (UHF). The paper presents the result of modeling, engineering, manufacturing and testing models of microwave ILG which form a complete functional basis. A numerical simulation microwave model ILG, which implements the functions “AND“, “XOR“ and “NOT“, has been carried out. The model consists of four types microwave functional units: circulators, single-stage ring power adder and power take-off elements, which are directional couplers, with lateral coupling and with a given branch coefficient. The finite integration method in the time domain for numerical system modelling is used to confirm the operational principle of ILGs and their realizability. ILG mock-ups implement the functions “AND“, “XOR“ and “NOT“. The identity of the intensity values corresponding to the logical “0“ and “1“, generated by different elements, is observed. The execution duration of logical operations is determined by the duration of the pulse propagation in the waveguide. The use of reactive elements in the design of the ILG makes it possible to minimize the loss of microwave energy during the propagation of an electromagnetic pulse.
