Past chastotali filtrlar RF koaksial yuqori chastotali mikrostripli mikroto'lqinli millimetr to'lqinli radiochastotali to'xtatilgan chiziqli to'lqin qo'llanmasi
RF past chastotali filtr - bu yuqori chastotali signallarni olib tashlash orqali past chastotali signallarni saqlaydigan signalni qayta ishlash filtri. U ma'lum bir chegaradan past chastotali signallarning o'tishiga imkon beradi, lekin bu chegaradan yuqori chastotali signallarni rad etadi.
Radiochastotali past chastotali filtrlarning xususiyatlari:
1. Faqat ma'lum bir chastotadan past signallar o'tishi mumkin, shu chastotadan yuqori signallar esa filtrlanadi yoki kuchsizlantiriladi.
2. Past chastotali signallardan o'tayotganda, fazada deyarli o'zgarish bo'lmaydi.
3. Odatda, telekommunikatsiya past chastotali filtrlarni yaratish uchun bir yoki bir nechta kondensator va induktorlardan foydalaniladi.
Koaksial past chastotali filtrlarni qo'llash:
1. Silliq signal
Yuqori chastotali past chastotali filtr asosan signalni yumshatish uchun ishlatiladi, u yuqori chastotali signaldagi shovqinni olib tashlashi mumkin, shunda signal yanada barqaror bo'ladi. Silliq signal talab qilinadigan hollarda, mikrostripli past chastotali filtr yuqori chastotali shovqinni olib tashlashi mumkin, shu bilan tizimni yanada ishonchli va barqaror qiladi.
2. Shovqinni kamaytirish
Past chastotali filtr past chastotali signalga ta'sir qilmaydi, past chastotali signalni saqlab qolganda, yuqori chastotali shovqinni filtrlash mumkin. Audio yoki tasvirni qayta ishlashda past chastotali filtrlar shovqinni filtrlashi va qayta ishlangan signalni aniqroq qilishi mumkin.
3. Xatolikni kamaytiring
Past chastotali filtr xatoni kamaytirishi mumkin, ayniqsa aniq asboblarni o'lchash uchun mos keladi. Ba'zi talabchan o'lchovlarda past chastotali filtr shovqin, shovqin va boshqa omillarni olib tashlashi mumkin, shunda o'lchov natijalari aniqroq va ishonchli bo'ladi.
4. Keng qo'llanilish doirasi
Millimetr to'lqinli past chastotali filtr deyarli hamma joyda, audiodan tasvirgacha, aloqadan boshqaruvgacha juda keng qo'llanilish doirasiga ega. Masalan, bazaviy polosali signalni qayta ishlashda kichik o'lchamli past chastotali filtr zarur.
Aloqada, to'xtatilgan past chastotali filtr aloqa sifatini ta'minlash uchun yuqori chastotali shovqin, shovqin va boshqalarni filtrlashi mumkin; Boshqarish sohasida, chiziqli past chastotali filtr signalni tekislash va shovqinni filtrlash uchun ishlatilishi mumkin.
QualwaveDC-50GHz chastota diapazonida mikroto'lqinli past chastotali filtrlarni yetkazib beradi. To'lqin yo'naltiruvchi past chastotali filtrlar ko'plab dasturlarda keng qo'llaniladi.
