Tasmani rad etish filtrlari RF koaksial taroqsimon interbarmoqli mikrostripli mikroto'lqinli millimetr to'lqinli radiochastotali spiral osilgan chiziq
Tasmani rad etish filtri
Diapazonni rad etish filtri - bu signalni qayta ishlashda ma'lum bir chastota diapazonidagi signalning kattaligini bostirish va boshqa chastota diapazonlaridagi signallarning o'tishiga imkon berish uchun ishlatiladigan filtr. Diapazonni rad etish filtrining ishlash printsipi chastota domenidagi kirish signalini tahlil qilish va belgilangan chastota diapazoniga muvofiq signalning amplitudasini tanlab bostirishdan iborat bo'lib, shu bilan belgilangan chastotada shovqinni kamaytirishga erishiladi.
Tasmali rad etish filtrlari qo'shimcha ravishda taroqsimon tasmali rad etish filtrlari, barmoqlararo tasmali rad etish filtrlari, spiral tasmali rad etish filtrlari, osma chiziqli tasmali rad etish filtrlariga bo'linadi.
Quyida millimetr to'lqin diapazonini rad etish filtrlarining asosiy xususiyatlari keltirilgan:
1. Muayyan chastota diapazonida signal uzatilishini bloklash: diapazonli to'xtash filtri nolga teng uzatish funksiyasiga ega emas, lekin markaziy kesish chastotasida uzatish funksiyasi minimal qiymatiga ega. Shuning uchun u markaziy chastota diapazoni orqali signal uzatilishini bloklashi mumkin.
2. Boshqa chastota signallarining o'tishiga ruxsat bering: Markaziy chastota diapazonidan tashqari, diapazonni to'xtatuvchi filtr boshqa barcha chastotalarning signallarining o'tishiga imkon beradi. Bu shovqin, shovqinni yo'qotish va chastotaga javob berishning ma'lum talablariga javob berish uchun diapazonni to'xtatuvchi filtrlardan foydalanishga imkon beradi.
3. Kichik to'lqin buzilishi: boshqa filtr turlari bilan solishtirganda, tarmoqli to'xtash filtrlari kichikroq to'lqin buzilishiga ega. Bu shuni anglatadiki, ular filtrdan o'tayotgan signalning shakli va amplitudasini yaxshiroq saqlab qolishi mumkin.
4. Keng polosali signallarni qayta ishlash: Polosali to'xtash filtri keng polosali signallarni qayta ishlash uchun ishlatilishi mumkin, chunki u chastota komponentlarining ko'p qismini saqlab qolishi va faqat ma'lum bir chastota diapazonini bloklashi mumkin.
5. Fazaviy javob: Polosa-stop filtrining fazaviy javobi uning dizayni va amalga oshirilishiga bog'liq, lekin odatda past chastotali filtr va yuqori chastotali filtr o'rtasida bo'ladi.
Mikrostripli tasmasimon rad etish filtrlarini qo'llash:
1. Elektr signallarini qayta ishlash: RF diapazonini rad etish filtrlari elektr signallarini qayta ishlashda ma'lum shovqin chastotalarini filtrlash uchun ishlatilishi mumkin, shu bilan signal sifatini yaxshilaydi.
2. Radioaloqa: Radioaloqada radiochastota diapazonini rad etuvchi filtrlardan signallardagi keraksiz chastotalarni filtrlash va shu bilan aloqa sifatini yaxshilash uchun foydalanish mumkin.
3. Yuqori chastotali elektronika: Kerakli elektron ishlashiga erishish uchun kontaktlarning chastota javobini sozlash uchun diapazonli to'xtatuvchi filtrlardan foydalanish mumkin.
4. Tibbiy asbob-uskunalar: Koaksial tasmali rad etish filtrlari elektrokardiogramma asboblari kabi tibbiy asbob-uskunalarda mushaklar va boshqa tashqi shovqin manbalaridan chastotalarni filtrlash uchun ishlatilishi mumkin.
