Zosefera za RF ndi Microwaveamagwiritsidwa ntchito kusefa zizindikiro zosafunikira kuti zilowe mudongosolo. Ndi kuwonjezeka kwa miyezo yopanda zingwe m'magulu omwe alipo, zosefera tsopano zimagwira ntchito yofunika kwambiri ndipo zimayenera kuchepetsa kusokoneza. Amapangidwa kuti azigwira ntchito pafupipafupi komanso kulola / kuziziritsa ma siginecha a RF pama frequency osiyanasiyana. Zosefera za RF zili ndi mitundu iwiri ya ma frequency band - passband ndi stopband. Zizindikiro zomwe zili mu bandi yodutsa zimatha kudutsa mosadukiza pang'ono pomwe ma siginecha omwe ali mumayendedwe oyimitsa amakumana ndi kutsika kwambiri.

SefaMtundu: Pali mitundu yosiyanasiyana ya zosefera za RF - Zosefera za Band Pass, Zosefera za Low Pass, Zosefera za Band Stop, Zosefera za High Pass etc. Mtundu uliwonse umagwira ntchito mosiyana.

Zamakono: Malingana ndi zofunikira zomwe zimagwiritsidwa ntchito komanso kukula kwa makina opanda waya pali mitundu yambiri ya fyuluta - Zosefera za Notch, Zosefera za SAW, Zosefera za Cavity, Zosefera za Waveguide etc. Aliyense ali ndi katundu wosiyana ndi mawonekedwe osiyanasiyana.

Passband Frequency (MHz): Awa ndi ma frequency angapo pomwe ma siginecha amatha kudutsa mosachepera pang'ono.

Stopband Frequency (MHz): Awa ndi ma frequency angapo pomwe ma siginecha amachepetsedwa. Kukwera kwapamwamba kumakhala bwinoko. Izi zimatchedwanso kudzipatula.

Kutayika kwa Insertion (dB): Ndiko kutayika komwe kumachitika pomwe siginecha ikuyenda pama frequency a passband. Kutsika kwa kutayika kumapangitsa kuti fyuluta igwire bwino.

Stopband Attenuation (dB): Ndiko kuchepetsedwa kwa ma siginecha omwe amakhala poyimitsidwa ndi fyuluta yomwe wapatsidwa. Kukula kwa kuchepetsedwa komwe kumakumana ndi ma sign kumatha kusiyanasiyana malinga ndi kuchuluka kwake.

Chilichonse RF yalemba zosefera za RF kuchokera kwa opanga otsogola pamsika. Sankhani mtundu wa fyuluta ndiyeno gwiritsani ntchito zida zofufuzira za parametric monga Frequency, Insertion Loss, Mtundu wa Phukusi ndi Mphamvu kuti muchepetse zosefera kutengera zomwe mukufuna. Tsitsani ma sheets ndikuwona zomwe mukufuna kuti mupeze zosefera zoyenera pa pulogalamu yanu.

Titha kusinthanso magawo a rf passive malinga ndi zomwe mukufuna. Mutha kulowa patsamba losintha kuti mupereke zomwe mukufuna.
