PURPOSE: A non-harmonic frequency coupler is provided to manufacture a desired coupler by allowing a user to use a simulation program ADS and manufacture a PCB. CONSTITUTION: A non-harmonic frequency coupler is a coupler adopting a lowpass filter. The length and thickness of a line is manufactured in current cellular phone frequency band by using a microstrip line based on a micro wave theory. The Harmonic Frequency is removed by using Lumped Element, and a user design and simulates with ADS(advanced Design System) by using the current coupler. |
