BROADBAND SIGNAL GENERATOR Russian patent published in 2018 - IPC H03B1/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio engineering and can be used as signal formers in transmitters of communication devices for various purposes. For this purpose, a generator containing n renovate formers of constant voltage (1.1–1.n), outputs of which are connected to inputs of corresponding n voltage-controlled generators (VCG) (2.1–2.n), series-connected bandpass filter (5) and load (6), output of which is an output of the device, in this case, inputs of renovate formers of constant voltage (1.1–1.n) are inputs for control voltages, n electronic keys (3.1–3.n), inputs of which are connected to outputs of corresponding n VCGs (2.1-2.n), multiplier (4) whose output is connected to input of bandpass filter (5), and outputs of electronic keys (3.1–3.n) from 1 to k-th are combined and connected to the first input of multiplier (4), and outputs of electronic keys from k+1^st to n-th are combined and connected to the second input of multiplier (4); also, control device (7) is connected, output of which is connected to the second inputs of electronic keys (3.1–3.n).

EFFECT: technical result is to ensure the formation of a broadband signal with common-mode frequency components with uniform frequency response over time, commensurate with the period corresponding to the lower frequency of the signal.
