| Stdio-Wcalc: microstrip_syn microstrip_syn - Single microstrip transmission line synthesis ## SYNOPSIS microstrip_syn z0 w h l tmet rho rough er tand f flag ## PARAMETERS ### INPUT PARAMETERS z0 : desired characteristic impedance (Ohms) w : width of microstrip line (meters) h : substrate thickness (meters) l : lentgh of microstrip line (meters) tmet : metal thickness (meters) rho : resistivity of the metalization (relative to copper) rough : conductor surface roughness (meters-rms) er : substrate relative permitivitty tand : substrate loss tangent f : synthesis frequency (Hz) flag : indicates which parameters should be optimized flag=1 : synthesize the metal width flag=1 : synthesize the substrate thickness flag=2 : synthesize the substrate dielectric constant flag=3 : synthesize the metal length ### OUTPUT VALUES w_out : Calculated width of microstrip line (meters) h_out : Calculated height of microstrip line (meters) l_out : Calculated length of microstrip line (meters) er_out : Calculated substrate relative permitivitty of microstrip line ## DESCRIPTION Function to synthesize the physical dimenstions of a single microstrip transmission line to achieve a desired characteristic impedance and electrical length. The desired characteristic impedance and some of the physical dimensions of the microstrip line are given as inputs and the remaining dimensions are calculated. ``
