Abstract
The invention refers to the radio electronics and may be used for introduction of the controllable phase shift on the path of a signal.Summary of the invention consists in that the phase shifter comprises an operational amplifier 1, a condenser 3 having one contact connected conjointly with one contact of the first resistor 2 to the noninverting input of the amplifier 1, a second resistor 4 having one contact connected to the output of the operational amplifier 1 and the second contact to the inverting input thereof and a third resistor 5 connected between the inverting input of the operational amplifier 1 and the input of the phase shifter. The phase shifter additionally comprises a negative resistance converter 6 provided with two output terminals 7 and 8, two input terminals 9 and 10 and a control input 11, as well as a resistor 12 connected to the input terminals 9 and 10 of the converter 6. The output terminal 7 of the converter 6 is connected to the second contact of the first resistor 2, the output terminal 8 of the converter 6 is connected to the common electric wire, and the second contact of the condenser 3 is also connected to the input of the phase shifter.The negative resistance converter 6 possesses a conversion ratio controllable in the value range from 0 up to -K0 through the control input 11 and the value of resistance of the resistor 12, connected to the input terminals 9 and 10 of the converter 6, is selected so that the maximum value of the negative resistance module reproduced by the converter 6 on the output terminals 7 and 8 should be two times greater than value of resistance of the first resistor 2.The result of the invention consists in providing the phase shift introduction in the control interval from 0 to 360° on the path of a signal.
