The use of high performance Integrated Passive Devices (IPD) allows an optimum solution in the tradeoff between integration and flexibility for design modification. The paper presents the integration of sub-circuits into IPD's for WLAN and distributed broadcasting satellite (DBS) applications on Liquid Polymer Crystal (LCP)-based organic substrate technology. An integrated diplexer-coupler-harmonic filter for dual-band WLAN applications and a diplexer-balun chipset for DBS applications are presented. The WLAN IPD measures 5x6mm, exhibits directivities of 27dB and 16dB in the 2.4GHz and 5GHz band, and provides 45dB of second harmonic rejection. The DBS diplexer provides 45dBc rejection. Finally, the 2xl.25mm DBS balun utilizing high-inductive coupling shows a measured amplitude and phase balance of 0.5dB and 50 and a minimum return loss of 10dB.

This paper presents a parasitic-aware design method using parameterization of embedded passive devices on multilayer organic substrates. The parameterization enables designers to map electrical circuits into high quality physical layouts and to use parasitics of embedded inductors and capacitors for high quality RF design. The proposed method was demonstrated through design of compact, high performance bandpass filter on multilayer organic substrates.
