Kugirango uhuze ibyifuzo byoroshye, Jingxin atezimbere akayunguruzo keza kugirango umukiriya yikemure wenyine, kandi atanga umurongo ngenderwaho wo kuyihuza neza nkurugero rukurikira rwa VHF muyunguruzi.
1. Kongera gutunganya uburyo bwaAkayunguruzoJX-SF1-152174-215N
Akayunguruzo kagenewe guhuza hejuru ya 15 MHz kandi ikagira umurongo wa passband ya 8 MHz.
2. Ibikoresho bisabwa
Umuyoboro wisesengura ushobora kwerekana igihombo cyo kwinjiza no gutakaza igihombo.
Muri passband, igihombo cyo gushiramo kigomba kuba ≤ 1.7dB;igihombo cyo kugaruka kigomba kuba ≥20dB
Ibikoresho by'intoki ： 6mm ifungura-impera;Amashanyarazi
3. Kongera guhuza uburyo
Ubu buryo buzasobanura inzira yakoreshejwe kubice byahujwe mbere na centre yumurongo wa 160.3MHz, hamwe numuyoboro mugari wa 8 MHz.
Nkuko bigaragara ku gishushanyo cya 1, imiyoboro ya resonator igenwa nka F1, F2, F3, F4, na F5.Imiyoboro yo guhuza igena inshuro yo hagati ya buri pole, nkuko imigozi yo guhuza igenda imbere, inshuro zizaba nke, mugihe imigozi yo guhuza igenda hanze, kandi numurongo uzaba mwinshi.
F12, F23, F34, F45 ni imiyoboro ihuza, iyi miyoboro igena umurongo wa passband, imiyoboro igenda imbere, kandi irashobora kwagura uruhande rwiburyo rwumuhanda, imigozi igenda hanze irashobora kugabanya uruhande rwiburyo rwumuhanda.
Igishushanyo 1
Intambwe ya 1: Huza akayunguruzo JX-SF1-152174-215N hamwe nisesengura ryurubuga rwashyizweho, nkuko bigaragara ku gishushanyo cya 2
Igishushanyo 2
Intambwe ya 2 ： Shiraho inshuro nkuru isabwa ya 160.3MHz hamwe nubunini bwa 8MHz
Intambwe3: Inshuro yambere ya 160.3MHz ± 4MHz, Inshuro yo kwangwa hanze ya 160.3 ± 9MHz na 160.3 ± 14MHz irashobora kugaragara murwego rwumurongo, nkuko bigaragara ku gishushanyo cya 3
Igishushanyo 3
♦Intambwe zikurikira ninzira yo gukemura inshuro nkuru kuva 160.3MHz kugeza152MHz
1. yimuka ibumoso.
Igicapo 4 kirerekana ihinduka rya buri cyuma gikurikirana kuri 152MHz ± 4MHz.
Igicapo 4
1) Nyuma yo guhinduranya kuri tuning screw F5, komeza ukoreshe 6mm spanner irekure gato ibinyomoro; screwdriver izunguruka imigozi ya tuning, ihindure igihombo cyo kugaruka kubiciro byagenwe, Niba igihombo cyo kwinjiza no gutakaza ibumoso bidashobora kugera kubiciro byagenwe, the igihombo cyo gushiramo no gutakaza igihombo kirashobora kugabanuka nukuzenguruka kumasaha cyangwa kuruhande rwamasaha yo guhuza imigozi F12, F23, F34 na F45, nkuko bigaragara mumashusho 5.
Igicapo 5
Igishushanyo cya 6 ni igishushanyo cyuzuye cya centre yumurongo kuri 152MHz;umurongo wa 8MHz
Igicapo 6
♦Intambwe zikurikira ninzira yo gukemura inzira yumurongo wo hagati kuva160.3MHzKuri174MHz
1） Umuvuduko uva hasi ugana hejuru, mukurikirane kuzenguruka imigozi yisaha F1 、 F2 、 F3 、 F4 、 F5 kugeza 174MHz ± 4MHz, imiyoboro yose yo guhuza igenda hanze, inshuro ya cavit izahinduka muri rusange kuva hasi kugeza hejuru, passband igenda. iburyo.
Igicapo 7 kirerekana ihinduka rya buri cyuma gikurikirana kuri 174MHz ± 4MHz
