In the paper a filter on the parallel resonant circuit on L-, C-negatrons is suggested. The parallel resonant circuit on L-, C-negatrons is investigated. Stability of the contour and frequency characteristics are considered. Experimental researches of the contour on the circuitry analogues of negatrons are conducted. Use of L-, C-negatrons improves the frequency-selective properties of the filter. Simulation of the filter on circuitry analogues of L-, C-negatrons on operational amplifiers LF400C is done. The simulation results showed improvement of frequency selectivity of the filter characteristics by reducing the phase distortion.
