Abstract

A multiplexer structure (500) includes a passive substrate (508). The multiplexer structure (500) may also include a high band filter (502) on the passive substrate. The high band filter (502) may include a 2D planar spiral inductor(s) (530, 540) on the passive substrate. The multiplexer structure (500) may further include a low band filter (504) on the passive substrate. The low band filter (504)may include a 3D through-substrate inductor (510, 520) and a first capacitor(s) on the passive substrate. The multiplexer structure (500) may also include a through substrate via(s) (VIA) coupling the high band filter (502) and the low band filter (504).

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] US Provisional Patent Application No. 62 / 271,893, entitled "MULTIPLEXERDESIGN USING A 2D PASSIVE ON GLASS FILTER INTEGRATED WITH A 3D THROUGH GLASSVIA FILTER," filed December 28, 2015 as required by this application under 35 U.S.C. §119(e) , the disclosure of which is expressly incorporated herein by reference in its entirety. technical field [0003] The present disclosure generally relates to integrated circuits (ICs). More specifically, the present disclosure relates to multiplexer designs using 2D passive on glass (POG) filters integrated with 3D through glass via (TGV) filters. Background technique [0004] For wireless communications, duplexers can help process signals carried in a carrier aggregation system. In a carrier aggregation system, signals are communicated using both high frequency and low frequency bands. In chipsets, a duplexer is usually inserted between the antenna and the tuner (or radio frequen...
