This paper describes the therapeutic device developed at the Institute of Electronic Engineering and Nanotechnologies ―D. Ghitsu‖ (IIEN). The device is based on the parallel-strip technology. This technology is effective for the designing, testing, and subsequent manufacturing of low intensity microwave generators to use in medicine, veterinary medicine, microbiology, etc. The proposed device differs from those developed and used previously by the fact that it combines a number of known and new methods for elaboration, which prove this device with new properties. We do not use a waveguide (metal mechanical device) in the generator-module as the basic working environment of the active elements (generators), instead, we use a plate with parallel stripes. The plate with parallel strips contains two substrates, but the passive elements, such as inductances and capacities, form a composite circuit, where the active elements (transistors, diodes varicap, etc.), form an auto-oscillating system that generates microwaves.
