The band around 300 GHz has already been identified, and the first components and soon transmission systems will emerge, based on multiple technologies, which may be based on a combination of silicon and III-V technologies. One of the key points of these systems is the production of power components in the 300 GHz range in order to increase the range of these systems. To assess the performance of active circuits, it is essential to measure intermodulation in two-tone injection. The principle of this type of measurement is to inject two frequencies into the component to be measured at the same time. However, achieving bi-tone generation at 300 GHz is not easy. The technique developed here involves using an optoelectronic source capable of converting an optical signal at 1.55 \u00b5m (optical fibre wavelengths) into a 300 GHz signal.<\/p>\n<\/blockquote>\n<\/div><\/section><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-16dm33g-a48459541c4f063080e0e5c76c322ec7\">\n.flex_column.av-16dm33g-a48459541c4f063080e0e5c76c322ec7{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-16dm33g-a48459541c4f063080e0e5c76c322ec7 av_two_fifth  avia-builder-el-2  el_after_av_one_full  el_before_av_three_fifth  first flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-kmenawb9-26a97ac33fea6e6b0508af0cbdf2bd3e'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p style=\"text-align: center;\"><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2021\/03\/graph_gd.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-medium wp-image-44845\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2021\/03\/graph_gd-300x229.jpg\" alt=\"\" width=\"300\" height=\"229\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2021\/03\/graph_gd-300x229.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2021\/03\/graph_gd-16x12.jpg 16w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2021\/03\/graph_gd.jpg 584w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<\/div><\/section><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-vj60ks-666a43006a5b3408d8f2a1dfde9fe1a6\">\n.flex_column.av-vj60ks-666a43006a5b3408d8f2a1dfde9fe1a6{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-vj60ks-666a43006a5b3408d8f2a1dfde9fe1a6 av_three_fifth  avia-builder-el-4  el_after_av_two_fifth  avia-builder-el-last  flex_column_div av-zero-column-padding  column-top-margin'     ><section  class='av_textblock_section av-kmenbaid-4d55742e1952b1e893fb7015a6b2cc40'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>This type of component also makes it easy to generate a series of frequencies at the same time when subjected to several input wavelengths. With this dual-frequency (\"dual-tone\") source in place, it has been shown for the first time [REF] that IP3 and IP5 (non-linearities of order 3 and 5) characterisation of active components becomes possible in the 300 GHz band using this technique. In addition, since the optoelectronic approach also enables the noise figure of the circuit to be measured, the noise\/power measurement is obtained on a given device, in one go. The component tested is an active circuit using HEMT technology at 300 GHz, performing the LNA (low-noise amplifier) function.<\/p>\n<p>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-13ewzjw-c896afcef377fb020200a5a80b92f436\">\n.av_font_icon.av-13ewzjw-c896afcef377fb020200a5a80b92f436{\ncolor:#800000;\nborder-color:#800000;\n}\n.av_font_icon.av-13ewzjw-c896afcef377fb020200a5a80b92f436 .av-icon-char{\nfont-size:30px;\nline-height:30px;\n}\n<\/style>\n<span  class='av_font_icon av-13ewzjw-c896afcef377fb020200a5a80b92f436 avia_animate_when_visible av-icon-style- avia-icon-pos-left avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue803' data-av_iconfont='entypo-fontello' ><\/span><\/span>H.
