مخمّد ثابت عالي القدرة

في بعض الوحدات أو أنظمة RF، يخفض المخمّد قدرة الخرج دون تشويه شكل الموجة أو البيانات عندما تكون قدرة الخرج مرتفعة جدًا وقد تتلف النظام أو المعدات. ولا يقتصر دور المخمّد على تحسين مطابقة الممانعة وضمان موثوقية الدائرة، بل يمكن استخدامه أيضًا لمواءمة المستوى بين دائرتين أو جهازين مختلفين. توفّر Psatek مخمّدات ثابتة تعمل من 1 W إلى 500 W، بترددات من DC إلى 67 GHz، مع موصلات متنوعة للاختيار. يرجى التواصل مع فريق المبيعات (sales@psatek.com) للحصول على عرض سعر.
