Hatariho akayunguruzo mu mperuka ya RF imbere, ingaruka zo kwakira zizagabanuka cyane. Kugabanyirizwa bingana iki? Muri rusange, hamwe na antenna nziza, intera izaba byibuze inshuro 2 ibibi. Kandi, iri hejuru ya Antenna, kubangamira cyane! Kuki? Kuberako ikirere cyumunsi cyuzuyemo ibimenyetso byinshi, ibi bimenyetso birahagarika imbere yakira umuyoboro. Kubera ko filteri yimbere ari ngombwa, uburyo bwo gukora filteri yimbere? RF inganda shobuja shobuja kukwigisha! Ariko, filteri yimbere-yatsinda rya 435mhz ntabwo byoroshye kongeraho. Reka dutangire isesengura
Iyi ni urutonde rwa band-pass spoter hamwe na capuct ya capuct couporling hamwe ninshuro ya 435mhz. Bitewe no gukoresha indumisi iboneka mubucuruzi (ifite Q Agaciro ka GAPO kugeza 70), igihombo cyinjiza ni kinini cyane, kigera kuri -11DB, nicyandi gishobora guhinduka (kirashobora guhinduka mumyanda ihagaze). Kubwibyo, kumva ko uwakiriye agira ingaruka cyane, kuko kumva ko uwakiriye afitanye isano na 0.5, ariko niba ihangane ryumurongo wimbere rishobora kuyungurura urusaku na 11DB. Ntabwo rero ari gake kubona imwe yakoreshejwe gutya. Reba kuri iyi shusho:
Komeza ibindi bipimo, Indumu isimburwa no gukandagira neza, nubwo ingano ari nini, ariko igihombo cyinjijwemo kiba -5, gikoreshwa cyane, ariko biracyagoye cyane gukora. Kuberako: ubushobozi bwa coupling hejuru ni 0.2p gusa, kandi ubushobozi bwiki bushobozi ntabwo bworoshye kugura, kugirango ubashe gukurura imbaraga kuri PCB, zizana ingorane zo gutsinda 1. Ndetse na Muganga wa 12Nh ntabwo aribyiza cyane kumuyaga, kandi bigomba kuba ubusa no guhungabana, kandi ntabwo ari byiza kumenya niba hari ibintu bidahagije. Inductance iracyari nini, ibipimo by'ubwo buryo bwo kubonana cyane, kandi impinduka nke zizagira ingaruka kumikorere. Noneho byagenda bite niba ushobora gukomeza kongera agaciro q agaciro ka ISductor, kandi hariho inzira yo gukomeza kugabanya ubushobozi bwa coupling? Hanyuma ugabanye igitambaro gito. Ibintu byaba nkibi bikurikira:
Inductance q agaciro k'iyi mibare ihita iba 1600, kandi inductinance nayo iba nziza cyane, iyi kiyunguruzo kirashobora kwemeza ko guhitamo no kwizirikana no kwizirikana ingufu mukigo cya IC, gitunguranye gikurura intera. Imikorere myiza, ariko ingano ni microstrif nini cyane
Umukino wa Spiral Spoter kuri uyu muyunguruzi, abantu bake kandi bake bazashushanya rwose mubushinwa, kandi software irashobora kuba ihujwe neza. Ubwa mbere, ifoto ibanziriza itangiza serivise nyayo kubikoresho bya mobile ya 435mz. Mubyukuri, muyunguruzi neza ugomba kuba yarakozwe neza, tuzashushanya uburyo bwiza bwo mu rurimi rw'ikinyabuzima 2 na 4-cavit kuri iyi mashini yo kwipimisha.
