Past o'tish filtrlari RF koaksial yuqori chastotali mikrotasma Mikroto'lqinli millimetrli to'lqinli radiochastota to'xtatilgan chiziqli to'lqin qo'llanmasi
RF past o'tish filtri yuqori chastotali signallarni olib tashlash orqali past chastotali signallarni saqlaydigan signalni qayta ishlash filtridir. U chastotasi ma'lum chegaradan past bo'lgan signallarni o'tkazishga imkon beradi, lekin bu chegaradan yuqori chastotali signallarni rad etadi.
Radiochastotali past o'tish filtrlarining xususiyatlari:
1. Faqat ma'lum bir chastotadan pastroq signallar o'tishi mumkin, bu chastotadan yuqori signallar filtrlanadi yoki zaiflashadi.
2. Past chastotali signallar orqali o'tayotganda, fazada deyarli hech qanday o'zgarish bo'lmaydi.
3. Odatda, bir yoki bir nechta kondansatör va induktorlar telekom past o'tkazgichli filtrlarni qurish uchun ishlatiladi.
Koaksiyal past o'tish filtrlarini qo'llash:
1. Silliq signal
Yuqori chastotali past o'tish filtri asosan signalni tekislash uchun ishlatiladi, u yuqori chastotali signaldagi shovqinni olib tashlashi mumkin, shunda signal yanada barqaror bo'ladi. Yumshoq signal zarur bo'lgan hollarda, mikrotasma past o'tish filtri yuqori chastotali shovqin shovqinini olib tashlashi mumkin, bu esa tizimni yanada ishonchli va barqaror qiladi.
2. Shovqinni kamaytirish
Past o'tish filtri past chastotali signalga ta'sir qilmaydi, past chastotali signalni saqlab, yuqori chastotali shovqinni filtrlash mumkin. Ovozni qayta ishlash yoki tasvirni qayta ishlashda past o'tish filtrlari shovqinni filtrlashi va qayta ishlangan signalni aniqroq qilishi mumkin.
3. Xatolikni kamaytiring
Past o'tish filtri xatoni kamaytirishi mumkin, ayniqsa nozik asboblarni o'lchash uchun mos keladi. Ba'zi talabchan o'lchovlarda past o'tish filtri shovqin, shovqin va boshqa omillarni olib tashlashi mumkin, shuning uchun o'lchov natijalari aniqroq va ishonchli bo'ladi.
4. Keng dastur doirasi
Millimetrli to'lqin past o'tish filtri deyarli hamma joyda audiodan tasvirgacha, aloqadan boshqarishgacha bo'lgan juda keng ko'lamli ilovalarga ega. Masalan, asosiy tarmoqli signalni qayta ishlashda kichik o'lchamdagi past o'tish filtri kerak.
Aloqada, to'xtatilgan past o'tish filtri aloqa sifatini ta'minlash uchun yuqori chastotali shovqin, shovqin va hokazolarni filtrlashi mumkin; Boshqarish sohasida chiziqli past o'tish filtri signalni tekislash va shovqinni filtrlash uchun ishlatilishi mumkin.
QualwaveDC-50GHz chastota diapazonida mikroto'lqinli past o'tkazuvchan filtrlarni etkazib beradi. To'lqinli past o'tish filtrlari ko'plab ilovalarda keng qo'llaniladi.
