Through phase control of each antenna element a focused signal beam can be created and maneuvered. Many applications in 5G, including beam forming, require many channels to transmit simultaneously which can cause unwanted perturbances in devices with poor linearity.\u00a0 Dielectric varactors linearity, defined by the IP3 parameter, is over 1000 times better than that of varactor diodes, essentially removing noise caused by non-linearity and making Tecdia\u2019s Varactors ideal for applications such as 5G small cell and macro cell antenna.<\/p>\n<p>&nbsp;<\/p>\n<h2><strong>High Frequency and Low Phase Noise VCO<\/strong><\/h2>\n<p>Voltage Controlled Oscillators (VCOs) are devices that utilize varactors to generate signals of a specified frequency range. The use of dielectric varactors reduces the insertion loss and therefore reduce the VCO\u2019s overall phase noise. Also, unlike varactor diodes, dielectric varactors act as variable capacitors when biased in either direction with the capacitance shift symmetric around 0V.\u00a0 This symmetry reduces overall components and simplifies circuits since the designer no longer needs to account a varactor diodes forward biased short mode.\u00a0 These advantages allow for higher frequency and lower phase noise VCOs than what has been possible with varactor diodes.<\/p>\n","protected":false},"featured_media":5624,"template":"","slc_category":[47,46],"class_list":["post-class-post-5586","post-class-slc","post-class-type-slc","post-class-status-publish","post-class-has-post-thumbnail","post-class-hentry","post-class-slc_category-new","post-class-slc_category-varactor"],"_links":{"self":[{"href":"https:\/\/us.tecdia.com\/products\/hf\/detail\/wp-json\/wp\/v2\/slc\/5586","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/us.tecdia.com\/products\/hf\/detail\/wp-json\/wp\/v2\/slc"}],"about":[{"href":"https:\/\/us.tecdia.com\/products\/hf\/detail\/wp-json\/wp\/v2\/types\/slc"}],"version-history":[{"count":25,"href":"https:\/\/us.tecdia.com\/products\/hf\/detail\/wp-json\/wp\/v2\/slc\/5586\/revisions"}],"predecessor-version":[{"id":5731,"href":"https:\/\/us.tecdia.com\/products\/hf\/detail\/wp-json\/wp\/v2\/slc\/5586\/revisions\/5731"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/us.tecdia.com\/products\/hf\/detail\/wp-json\/wp\/v2\/media\/5624"}],"wp:attachment":[{"href":"https:\/\/us.tecdia.com\/products\/hf\/detail\/wp-json\/wp\/v2\/media?parent=5586"}],"wp:term":[{"taxonomy":"slc_category","embeddable":true,"href":"https:\/\/us.tecdia.com\/products\/hf\/detail\/wp-json\/wp\/v2\/slc_category?post=5586"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
