FIELD: radio electronics.
SUBSTANCE: invention relates to radio electronics and can be used in wideband radio transmitters. Application of proposed circuitry allows eliminating the use of harmonics at the output of wideband amplifier incorporated with switch filters that will notably simplify configuring the frequency-adapted radio lines. Since the said configuration requires fast and frequent harmonics filter switching.
EFFECT: rejecting parasitic radiation from carrier-frequency harmonics at wideband amplifier output.
