Abstract:Miniature LTCC-integrated power monitors for dual-band operation in the 2.4-2JGHr und 4.9-5.9GHz Wireless-LAN bands are presented. The proposed low-cost circuit incorporates a direchonal coupler and a dual-diode power detector, all integrated in a very small size LTCC circuit. The measiired prototypes demonstrate high petformance with respect to power detector accuracy, temperature stabiliiy and dynamic range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
