RF chips, as the core component of modern wireless communication and navigation systems, directly influence the accuracy, stability, and integration level of the entire system. In GNSS (Global Navigation Satellite System) RF frontends, frequency synthesizers are key modules responsible for generating local oscillator signals, and fractional frequency division technology is essential for achieving high-precision and […]<\/p>\n","protected":false},"author":1,"featured_media":1396,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[30,31],"tags":[36],"class_list":["post-1444","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\/1444","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=1444"}],"version-history":[{"count":1,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/posts\/1444\/revisions"}],"predecessor-version":[{"id":1445,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/posts\/1444\/revisions\/1445"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/media\/1396"}],"wp:attachment":[{"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/media?parent=1444"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/categories?post=1444"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/tags?post=1444"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
