FIELD: radio communications; radio receivers and radio transmitters. SUBSTANCE: shaper has three accumulators 1, 2, 3, two multipliers 4, 5, digital-to-analog converter 6, amplifier 7, inverter 8, and control unit 9. Ring connection of units 1, 4, 2, 5, and 8 ensures recuperative computation of instant values of signal being shaped within broad frequency band and multibit analog-to-digital converter and amplifier with large amount of feedback applied to it make it possible to shaped constant-amplitude signal with high spectral characteristics. EFFECT: increased frequency band for shaping linear frequency-modulated signal with constant amplitude at output. 2 cl, 11 dwgi
