Problem statement. A substantial increase of modern GNSS receivers jamming resistance requires GNSS jammers output power augmentation. In such a case there are jammers output power limitations due to maximum available energetic parameters of modern medium-power high-frequency modular amplifiers applicable for jammers with satisfactory performance. 

Purpose. The design of circuit configuration oriented to jammer energy efficiency augmentation without output power and energy consumption increasing.

Results. A Hilbert transform based circuit configuration realizing complex-conjugate to original signal analytic signal with subsequent its radiation by means of doughnut-style antenna elements is designed. A multi-polarized signal formed by original signal and its orthogonal complement superposition can be obtained at the transmitter output. Waveform shaper and jamming signal transmitter structural circuits issued within a behavioral simulation environment are presented. Proposed circuit design effectiveness evaluation results are visualized.

Practical significance. A proposed circuit design potentially leads to GNSS jammers energy efficiency augmentation and spurious radiation level reduction.
