INTEGRATED CIRCUIT OF EXTREMELY HIGH FREQUENCY BAND Russian patent published in 2003 - IPC

FIELD: radio engineering. SUBSTANCE: proposed integrated circuit may be used for extremely high frequency receivers and transmitters or low-noise amplifiers. Single-end metallized microstrip line is made on substrate of λ₀/100<h<λ₀/30 thickness and face metallization in vicinity of waveguide window has specific configuration in the form of three series-connected microstrip line sections. Mathematical dependencies for calculating their length and width are given in description of invention. EFFECT: reduced input and output signal loss; enlarged operating frequency band. 1 cl, 3 dwg, 1 tbl
