The design documentation was developed, the layout was made, and an experimental study of the direction-finding receiver was conducted. A functional diagram and a description of the design are given. The method of the experiment is given. Shows the achievement of the following parameters: operating frequency range: centimeter; the dynamic range of the signals at the entrance 48 dB; the duration of the received pulses is not less than 0.1 µs; the irregularity of amplitude-frequency characteristics of not more than 5 dB.

The frequency divider for 32, operating in a range of frequencies 8-18 GHz is considered. The specifics of the schematic diagram is shown. The design and element base is described in short. The model is made and its experimental research is carried out. The technique and the block diagram of the experiment is described. Level of harmonics of an output signal is measured. For decrease of level of harmonics of the useful signal the low-pass filter of type SALF-580 is used. Presence of a parasitic output signal in the absence of an input signal is revelead.
