Filter low pass rf koaksial frekuensi tinggi microstrip microwave millimeter gelombang radio frekuensi radio stripgine tersuspensi waveguide
RF Low Pass Filter adalah filter pemrosesan sinyal yang mempertahankan sinyal frekuensi rendah dengan menghilangkan sinyal frekuensi tinggi. Ini memungkinkan sinyal dengan frekuensi kurang dari ambang batas tertentu untuk dilewati, tetapi menolak sinyal dengan frekuensi lebih besar dari ambang batas itu.
Fitur Filter Low Pass Frekuensi Radio:
1. Hanya sinyal di bawah frekuensi spesifik yang diizinkan untuk dilewati, sedangkan sinyal di atas frekuensi itu disaring atau dilemahkan.
2. Saat melewati sinyal frekuensi rendah, hampir tidak ada perubahan fase.
3. Biasanya, satu atau lebih kapasitor dan induktor digunakan untuk membangun filter low pass telekomunikasi.
Penerapan filter low pass koaksial:
1. Sinyal Mobil
Filter low pass frekuensi tinggi terutama digunakan untuk menghaluskan sinyal, dapat menghilangkan noise dalam sinyal frekuensi tinggi, sehingga sinyal menjadi lebih stabil. Dalam kasus di mana sinyal halus diperlukan, filter low pass microstrip dapat menghilangkan noise interferensi frekuensi tinggi, sehingga membuat sistem lebih andal dan stabil.
2. Reduksi
Filter low pass tidak akan mempengaruhi sinyal frekuensi rendah, sambil mempertahankan sinyal frekuensi rendah, noise frekuensi tinggi dapat disaring. Dalam pemrosesan audio atau pemrosesan gambar, filter low pass dapat menyaring kebisingan dan membuat sinyal yang diproses lebih jelas.
3. Mengurangi kesalahan
Filter low pass dapat mengurangi kesalahan, terutama cocok untuk pengukuran instrumen presisi. Dalam beberapa pengukuran yang menuntut, filter low pass dapat menghilangkan noise, gangguan dan faktor -faktor lain, sehingga hasil pengukuran lebih akurat dan dapat diandalkan.
4. Rentang aplikasi
Filter Low Pass Wave Milimeter memiliki berbagai aplikasi, dari audio ke gambar, dari komunikasi hingga kontrol, hampir di mana -mana. Misalnya, dalam pemrosesan sinyal baseband, diperlukan filter low pass ukuran kecil.
Dalam komunikasi, filter low pass yang ditangguhkan dapat menyaring kebisingan frekuensi tinggi, gangguan, dll., Untuk memastikan kualitas komunikasi; Di bidang kontrol, filter low pass stripline dapat digunakan untuk perataan sinyal dan pemfilteran noise.
Qualwavememasok filter low pass microwave dalam rentang frekuensi DC-50GHz. Filter Low Pass Waveguide banyak digunakan dalam banyak aplikasi.
