Inventia se refera la domeniul radioelectronicii si poate fi utilizata pentru introducerea defazajului reglabil in calea semnalului. Esenta inventieiconsta in aceea ca defazorul contine un amplificator operational 1, un condensator 3 conectat cu uncontact impreuna cu un contact al primului rezistor 2 la intrarea neinversoare a amplificatorului operational 1, al doilea rezistor 4, care este conectat cu un contact la iesirea amplificatorului operational 1 si cu al doilea contact la intrarea luiinversoare, si cel de-al treilea rezistor 5 conectat intre intrarea inversoare a amplificatorului operational 1 si intrarea defazorului. Defazorul contine suplimentar un convertor 6 de rezistenta negativa dotat cu doua cleme de iesire 7 si 8, doua cleme de intrare 9 si 10 si o intrare de comanda 11, precum si un rezistor 12, conectat la clemele de intrare 9 si 10 ale convertorului 6. Clema de iesire 7 a convertorului 6 este conectata la cel de-al doilea contact al primului rezistor 2, clema deiesire 8 este conectata la conductorul electric comun, iar cel de-al doilea contact al condensatorului 3 de asemenea este conectat la intrarea defazorului. Convertorul 6 de rezistenta negativa posedacoeficient de conversie reglabil prin intrarea decomanda 11 in intervalul de valori de la 0 pana la -K0, iar marimea rezistentei rezistorului 12 conectat la clemele de intrare 9 si 10 ale convertorului 6 se alege astfel incat marimea maxima a modulului rezistentei negative reproduse de convertorul6 la clemele de iesire 7 si 8 sa fie de doua ori mai mare decat marimea rezistentei primului rezistor 2. Rezultatul inventiei consta in asigurarea introducerii defazajului in intervalul de reglare dela 0 pana la 360° in calea semnalului.The invention relates to the field of radio electronics and can be used to introduce adjustable phase shift in the signal path. The essence of the invention is that the defroster contains an operational amplifier 1, a capacitor 3 connected uncontactly together with a contact of the first resistor 2 at the non-inverting input of the operational amplifier 1, the second resistor 4, which is connected with a contact at the output of the operational amplifier 1 and with the second contact at the inverter input, and the third resistor 5 connected between the inverter input of the operational amplifier 1 and the input of the phaser. The defroster additionally contains a negative resistance converter 6 equipped with two output terminals 7 and 8, two input clips 9 and 10 and a command input 11, as well as a resistor 12, connected to the input clips 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 is connected to the common electrical conductor, and the second contact of the capacitor 3 is also connected to the input of the defroster. The negative resistor converter 6 has the conversion coefficient adjustable by the input control 11 in the range of values from 0 to -K0, and the resistance size of the resistor 12 connected to the input clips 9 and 10 of the converter 6 is chosen so that the maximum size of the resistance module The negatives reproduced by the converter 6 at the output terminals 7 and 8 should be twice the size of the resistance of the first resistor 2. The result of the invention consists in ensuring that the phase shift is introduced in the adjustment range from 0 to 360 ° in the signal path.
