In order to cope with the worldwide shortage of the MLCC (multilayer ceramic capacitor), this paper proposes a methodology of integrated lattice balun using a high permittivity substrate material. It is well known that discrete radio frequency (RF) front-end circuits are composed of MLCCs and chip inductors in many electronic products. Inserting a high permittivity material to replace decoupling capacitors is an effective method. Another way to lessen the quantity of MLCCs is embedding an integrated RF front-end circuit instead of MLCCs, such as a balun, filter or duplexer. In this study, an integrated lattice balun was designed for DCS (digital cellular system) 1800 MHz. The simulation results show that the designed balun achieves a return loss $< -23$ dB, an insertion loss $\gt -0.25$ dB, a phase deviation form $180 \circ$ to $182 \circ$ and a magnitude deviation of less than 1.1 dB in the frequency range of DSC.
