Profillar pigitterlar RF koaxial yuqori chastotali mikrostrip mikroto'lqinli pechning millimetrli to'lqin chastotasi
RF past pas filter - bu past chastotali signallarni olib tashlash orqali past chastotali signallarni saqlaydigan signalni qayta ishlash filtri. Bu chastotalar bilan ma'lum bir chegaradan kam bo'lgan chastotalar bilan kamroq, ammo ushbu chegaradan kattaroq chastotalar bilan signallarni rad etadi.
Radio chastotasining past pilentlari:

2. Kam chastotali signallardan o'tayotganda, fazada deyarli o'zgarishlar bo'lmaydi.

Koaksial past pilmlarni qo'llash:
1.Smootchining signali
Yuqori chastota past pasli filtr asosan signalni tekislash uchun ishlatiladi, u yuqori chastotali signalni olib tashlashi mumkin, shunda signal yanada barqaror bo'ladi. Silliq signal kerak bo'lgan hollarda, mikrostrip kam mikrosfera filtri yuqori chastotali shovqinni olib tashlashi mumkin, shuning uchun tizim yanada ishonchli va barqaror qilib.
2. Qaytarilishni kamaytirish
Kam pas filtr past chastotali signalni saqlab qolganda, past chastotali signalni saqlab qolgan holda, yuqori chastotali shovqin chiqarilishi mumkin. Ovozni qayta ishlash yoki rasmlarni qayta ishlashda, past piltrlar shovqinni filtrlash va qayta ishlangan signalni aniqlatirishlari mumkin.
3. Xatoni bekor qiling
Pass filtri xatoni kamaytirishi mumkin, ayniqsa aniq asboblarni o'lchash uchun mos keladi. Ba'zilarning talab qilinadigan o'lchovlarda past pas filtr, o'lchov natijalari aniqroq va ishonchli ekanligi uchun shovqin, aralashuv va boshqa omillarni olib tashlashi mumkin.
4. Arizaning yo'nalishi
Millimetr to'lqinli pass filtrida juda keng qo'llanmalarga ega, audio rasmdan, deyarli hamma joyda boshqarish uchun muloqotdan. Masalan, bazadagi signalni qayta ishlashda, kichik o'lchamdagi past piltr kerak.
Aloqada to'xtatilgan past piltrti, yuqori chastota shovqin, aralashuv va boshqalar, aloqa sifatini ta'minlash uchun filtrlanishi mumkin; Tekshirish sohasida shpilzning past filtridan signal tekislash va shovqinli filtrlash uchun ishlatilishi mumkin.
NafaqaMikroto'lqinli pechni past chastota diapazonida DC-50GHZ diapazoniga etkazib beradi. To'lqinlovchining past pilmlari ko'plab dasturlarda keng qo'llaniladi.
