Abstract With the full implementation of the BeiDou-3 global satellite navigation system, the performance of RF chips has become crucial for ensuring the system\u2019s positioning accuracy and reliability. This paper delves into the role and optimized design of the \u03a3-\u0394 modulator in the BeiDou-3 RF chip, focusing on mitigating fractional spurs in the phase-locked loop (PLL) frequency synthesizer […]<\/p>\n","protected":false},"author":1,"featured_media":1279,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[30,31],"tags":[35],"class_list":["post-1280","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-industry-insights","category-blog","tag-jason-chen"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/posts\/1280","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=1280"}],"version-history":[{"count":1,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/posts\/1280\/revisions"}],"predecessor-version":[{"id":1281,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/posts\/1280\/revisions\/1281"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/media\/1279"}],"wp:attachment":[{"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/media?parent=1280"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/categories?post=1280"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wallisemi.com\/ko\/wp-json\/wp\/v2\/tags?post=1280"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
