السلام عليكم اخوتنا الكرام اشكركم جميعا على حسن ظنكم بى وبناء على طلب العزيز A71BR اقدم وبدون فخر عملاق مكبرات الهواة ولاول مرة على منتدى عربى او اجنبى وللمرة الاولى مكبر الف وات يعمل فى نطاق الهواة من 2 حتى 50 mhz ومن السهولة والبساطة حتى للاى شخص يعمله ومع قمة الاداء وصغر الحجم حيث المقاسات 12 فى 20 سم للوحة وخرج 1000 وات RF out كما اقده لكل اصدقائ من ال su الهواة المصرين
AR347 1000 WATT 2-50 MHZ AMPLIFIER
This amplifier design covers frequencies from 2 to 50 Mhz with a power output level of 1000 watts using RF power MOSFETs. The MRF154 used in this design is considered as a state of the art device. The MRF154 is usable up to 100 Mhz with a frequency range of 2 to 50 Mhz. Its applications include military communications, jammers, low channel TV, etc. Although the point of saturation is well over 1000 watts, the amplifier was tested for linearity at 800 watts.
