IyoFirita yeLC ye4500-5900MHzInoita kuti bandpass filtering iite nemazvo kuburikidza neLC network design, zvichiita kuti kutumirwa kweLC pass kuite zvishoma mukati me4500-5900MHz uku ichidzivirira out-of-band interference (>40dB releasing pa ±100MHz). Iyi LC Filter inobatanidza high-Q components kuderedza kurasikirwa kwekuisa uye kuwedzera kurambwa, ichichengetedza signal perfection. Electromagnetic shielding yayo inopa dziviriro mbiri—inodzivirira ruzha rwekunze ukuwo sarudzo yeLC Filter ichibvisa residual interference. Nekufananidza kwakaringana kwe50Ω impedance, kuratidzwa uye kukanganiswa zvinodzivirirwa. Kugadzirwa kwakasimba kunovimbisa kugadzikana kwethermal/mechanical (-40°C kusvika +85°C), zvichibvisa frequency drift. Pamwe chete, maficha aya anoita kuti LC Filter iyi ive mhinduro yakavimbika yekutaurirana kwakakosha.

LC Filter Zvimiro

Kusefa kweBhandi Rakakodzera
Firita yeLC ye4500-5900MHz inoshandisa dhizaini yepamusoro yeLC (inductor-capacitor) network kugadzira curve yekupindura yakapinza. Hunhu uhwu hwebhandi repamusoro hunobvumira masaini ari mukati me4500-5900MHz kuti apfuure nekuderedzwa kushoma uku achinyatso deredza mafrequency ari kunze kwebhendi iyi. Firita iyi inoita hunhu hwakanyanya hwekutenderera (kazhinji >40dB kurambwa pa±100MHz offset), ichigadzira "hwindo" rekudzivirira rinodzivirira kupindira kwechiteshi chiri pedyo.

Kubatanidzwa kweZvikamu zveHigh-Q
Nekushandisa zvikamu zvemhando yepamusoro (Q), LC Filter inoderedza kurasikirwa kwekuisa mukati mepassband uku ichinyanya kurambwa kunze kwebhendi. Ma inductors e-Q ane high-Q uye ma capacitor anoderedza kupararira kwesimba, achichengetedza kusimba kwechiratidzo uku achivhara ma frequency asingadiwe panguva imwe chete. Kubatsira uku kuviri kunoita kuti masaini anodiwa arambe akasimba ukuwo manyuko ekupindira achidzikira zvakanyanya.

Dhizaini yekudzivirira magineti
Kamuri kadiki keLC filter kanosanganisira electromagnetic shielding inodzivirira ruzha rwekunze rweRF kuti rusabatane munzira yesignal. Kudzivirira uku, pamwe chete neLC network's inherently frequency selectivity, kunoita kuti pave nematanho maviri ekudzivirira kukanganiswa—kutanga nekudzivirira ruzha rwekunze uye chechipiri nekubvisa chero masara asingadiwe.

Kugadzirisa Kufananidza Impedance
Kufananidza impedance chaiyo (kazhinji 50Ω) mukati meSefa yeLCDhizaini yaro inoderedza kuratidzwa kwechiratidzo kunogona kukonzera kukanganiswa kweintermodulation. Nekuchengetedza hunhu hwe impedance hwakafanana, LC Filter inodzivirira kugadzirwa kwezvigadzirwa zvitsva zvinokanganisa mukati mehurongwa hwekutaurirana, ichichengetedza kuchena kwechiratidzo.

Kugadzikana kweThermal uye Mechanical
Kugadzirwa kwakasimba kweLC filter kunovimbisa kushanda kwakasimba panguva dzakasiyana-siyana dzekupisa (-40°C kusvika +85°C) uye kushushikana kwemakanika. Kugadzikana uku kunodzivirira kutenderera kwema frequency kunogona kubvumira kupindirana kupinda mupassband, zvichichengetedza kudziviswa kwakavimbika kwekupindira munzvimbo dzakasiyana dzekushanda.

Zvakanakira zvefekitori

Si Chuan Keenlion Microwave ine sarudzo yakakura mu narrowband uye broadband configurations, inofukidza ma frequency kubva pa 0.5 kusvika 50 GHz. Yakagadzirwa kuti ikwanise kubata simba rekupinda rema watts gumi kusvika makumi matatu mu 50-ohm transmission system. Madhizaini e microstrip kana stripline anoshandiswa, uye akagadzirirwa kushanda zvakanaka.
