alt=\"\" width=\"267\" height=\"200\" \/><\/a>Non-linear 50GHz<\/h4>\n<p>To characterise the power performance of microwave devices, the centre has a non-linear vector network analyser operating up to 50GHz (Keysight N5245A). This system can be used to determine the Gp (power gain), Pout (power available at output) and Pae (power added efficiency) of transistors and amplifiers.<\/p>\n<p>As these parameters can only be determined in saturated mode, a high level of power is required to excite the device under test. Several amplifiers are available for this purpose, 2 amplifiers delivering 10W from 6 to 18GHz, 2 amplifiers delivering 2 and 5W from 40 to 44GHz and an amplifier delivering 12W between 39 and 40GHz.<\/p>\n<p>These measurements can be made in 'load-pull' mode by modifying the impedance presented at the output of the device under test, using two possible techniques: passive load-pull (tuner) or active load-pull (active load). This makes it possible to determine the optimum impedance for maximising Gp, Pout or Pae.<\/p>\n<p>All these measurements are possible in CW (continuous) or pulse (pulsed bias + pulse RF) mode, with a pulse width of 1\u00b5s and a duty cycle of 1%. Pulse measurements eliminate trapping and thermal phenomena, maximising the performance of the components under test.<\/p>\n<\/div><\/section><\/div><div  class='hr av-18rv8cn-21095300ef80299318be9ecb0a9a6210 hr-default  avia-builder-el-5  el_after_av_one_full  el_before_av_textblock'><span class='hr-inner'><span class=\"hr-inner-style\"><\/span><\/span><\/div><\/p>\n<section  class='av_textblock_section av-jion6v0u-9ffc29a5e7220c4ce9111b61e57f57e1'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><h4><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/06\/plate_forme_caracterisation_non_lineaire_94ghz.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignright wp-image-18539 size-full\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/06\/plate_forme_caracterisation_non_lineaire_94ghz.jpg\" alt=\"\" width=\"224\" height=\"168\" \/><\/a>Non-linear 94GHz<\/h4>\n<p>The characterisation centre also has a power characterisation system operating at 94GHz.
