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 5times6mm, 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 2times1.25mm DBS balun utilizing high-inductive coupling shows a measured amplitude and phase balance of 0.5dB and 5deg and a minimum return loss of 10dB
