In wireless communication systems, baseband chips and RF chips together form the core link for signal processing, both essential and interdependent. They have distinct functions but work in close collaboration to complete the conversion and transmission of data into radio waves. This article systematically explains the relationship between baseband chips and RF chips, revealing their collaborative mechanism in […]<\/p>\n","protected":false},"author":1,"featured_media":1354,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[30,31],"tags":[36],"class_list":["post-1364","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-insights","category-blog","tag-yvette-wu"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/posts\/1364","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/comments?post=1364"}],"version-history":[{"count":1,"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/posts\/1364\/revisions"}],"predecessor-version":[{"id":1365,"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/posts\/1364\/revisions\/1365"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/media\/1354"}],"wp:attachment":[{"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/media?parent=1364"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/categories?post=1364"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wallisemi.com\/vi\/wp-json\/wp\/v2\/tags?post=1364"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
