Introduction: RF chips (Radio Frequency chips) are the cornerstone of wireless communication systems. They are integrated circuits that convert RF signals into digital signals and vice versa, operating within the frequency range of 300kHz to 300GHz. These chips, including key components like transceivers, power amplifiers (PA), low-noise amplifiers (LNA), filters, RF switches, and antenna tuners, […]<\/p>\n","protected":false},"author":1,"featured_media":1340,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[30,31],"tags":[36],"class_list":["post-1339","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\/ko\/wp-json\/wp\/v2\/posts\/1339","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/comments?post=1339"}],"version-history":[{"count":1,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/posts\/1339\/revisions"}],"predecessor-version":[{"id":1341,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/posts\/1339\/revisions\/1341"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/media\/1340"}],"wp:attachment":[{"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/media?parent=1339"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/categories?post=1339"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/tags?post=1339"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
