[mskale15]

Hello

I need a help for my project please help me

Title: The design of wideband planar coupler operation at 1800Mhz
(this project involves the required bandwidth is 10% greater than the operation frequency).

coupling coefficient is 3dB
input/output impedance is 50 ohms
substrate is RT Duroid
Dielectric constant (Er) is 10.8
thickness(h) is 1.27mm
software: Agilent Advanced design system(ADS)

I need calculations and schematic for the above mentioned topic
