It is proposed to use half-round fixtures in order to excite straight-sight vertical slots in a narrow wall of a rectangular waveguide. The advantage of their use is this: lower level of cross-polarization radiation compared to variable slant slots, simplicity of parameters calculation, easy design performance and low reflection index. Variable conductivity is achieved by means of fixture fixture...
The researched type of microstrip directional coupler consists of a bridge joint in which the two lines are connected by means of coupled lines with short-circuited terminals. There is proposed in the document to use this type coupler in power control device for transmit-receive module of active phased-array antenna. Results of coupler modeling in dedicated programs for calculation of high-frequency...
The report describes multi-channel microwave devices for dividing and combining of high power, constructed by way of directional couplers series connection. The device analytical model is presented based on scattering matrix equipment, effects of amplitude and phase errors are described with regard to the device operation in power combining mode. Two variants of the device construction are proposed:...
A method for constructing Laplace transform models of dependent voltage and current sources has been developed. The method makes it possible to allow for non-zero initial values of input and output voltages or currents and their time derivatives. Examples of circuits containing multiple inputs and outputs are considered.
