Compact low and high band harmonic filters using an integrated passives device (IPD) technology

Compact harmonic low and high band filters for RF front-end transmit modules using an IPD technology are demonstrated. These filters exhibit excellent performance with insertion loss below 0.5 dB and harmonic rejection close to or greater than 20 dB over the entire frequency band. This paper also discusses the general design methodology for the cost-effective and efficient design of such devices
