Abstract
This article designs a dual transformer, which we can couple or tune to two arbitrary frequencies. We formulate this problem as a convex optimization problem, for which we express the reflection coefficient Ãin as a function of the frequency, the lengths of the transmission lines, and their characteristic impedances. We use the Convex Optimization and the Dichotomous Search algorithm that allows RL us to find the Z and Z 1 2 = Z of the transmission line sections used in the o Z 1 transformer. We show different results and include the case for operating frequencies of 700MHz (Band 7-LTE) and 1900MHz (Band 2-LTE).
