METHOD AND DEVICE FOR CORRECTING FREQUENCY RESPONSE CHARACTERISTICS Russian patent published in 2006 - IPC H03H7/38 

FIELD: radio communications and microwave engineering.

SUBSTANCE: proposed method that can be used in designing gain-frequency response correctors of matching devices and phase-frequency response correctors of receiving and transmitting communication channels at desired quantity of fixed frequencies to correct frequency response characteristics of these channels in 2N range of digital frequencies includes insertion of constant reactive components between member being matched on input end and member being matched on output end; connection of common input of ratio-N frequency-channel divider to member being matched on input end; connection of adder of N frequency channels on output end to member being matched; connection of each adder channel by means of channel matching device to respective same frequency by divider channel; generation of input impedances of each channel matching device for matching member being matched on input end at its frequency with standardized input impedances of each matching device on divider end, for matching member being matched on output end at its frequency with input impedances of each channel matching device on adder end, and for physical implementation, structure and parameters of channel matching devices being dictated by requirement to ensure desired values of transfer gain phases at 2N frequencies.

EFFECT: enlarged functional capabilities.
