Microwave yakadhindwa redunhu bhodhi uye RF PCB inoda kubatwa kwakasarudzika kwekuti vagadziri vako venguva dzose vangatadze kubata. Tinogona kushandisa yakakwira frequency laminates ine yakasimba kudhiraivha uye yepamusoro mhando kudzora zvakanaka kugadzira uye kukudziridza yako RF PCB kuona zvakajairika mashandiro.

Rayming rave rinotungamira RF microwave pcb mutengesi munyika, ichitarisa paHF pcb laminates. Rogers PCB, Teflon PCB, Arlon PCB, ndinogona kugadzira izvo zvaunoda.

Iyo RF pcb

< p&gt; Unogona kuvimba neRayming zvigadzirwa zvehunyanzvi nekuti isu tine timu, maturusi uye ruzivo rwekugadzirisa zvinhu zvakaomeswa zvine zvidikanwi zvine chekuita nemamishini, chafariz, magetsi uye zvimwe zvehunhu maitiro kupfuura zvinowanzoitwa FR-4 zvigadzirwa.

Isa zvigadzirwa zvako mumaoko akachengeteka nekuvimba wepamusoro rf microwave pcb mupiki anotarisa pane zvakanyanya kushivirira zvinodiwa uye anonunura rutsigiro rwaunoda nenguva, nguva dzese.

Nzwisisa kuti chii hf PCBS,

1. Hf PCBS kana kufonera microwave PCBS / RF PCBS / RF PCBS zvinoshandiswa zvakanyanya mukutaurirana zvisina waya, nhare dzisina waya uye satellite satellite, kunyanya 3G network, kuwedzera kudiwa kwemusika kwezvigadzirwa paHF PCBS. Nhasi, kudiwa kwema microwave zvinhu pcb magadzirirwo ari kuwedzera, uye isina waya yakakwira-kumhanya (yakakwira-frequency) kuwana data kuri kukurumidza kuve kudikanwa kwemisika yakawanda senge yekudzivirira, nzvimbo yekutengesa uye nhare mbozha. Shanduko dzemusika dzinoshanduka dzinoenderera nekutyaira kuvandudza kweyepamusoro frequency yakadhindwa wedunhu mabhodhi. Kunge 50+ GHz microwave maredhiyo kana ekudzivirira emhepo masisitimu, inogona zvakare kugadzirisa halogen-isina PCBS.

2. Iyo RF pc & Yakakwira frequency PCBS inogadzirwa kubva polytetrafluoroethylene (PTFE pcb), zvedongo-yakazadzwa fluoropolymers kana zvedongo-izere hydrocarbon thermosetting zvinhu zvine yakavandudzwa dielectric zvivakwa. Izvo zvinhu zvine yakaderera dielectric inogara ye2.0-3.8, yakaderera kurasikirwa chinhu uye yakanakisa yakaderera kurasikirwa maitiro, asi zvakare ine kuita kwakanaka, yakakwira girazi shanduko tembiricha, yakadzika kwazvo hydrophilic chiyero, yakanakisa kupisa kutsiga. Iko kuwedzera kwekuwedzera kwe PTFE pcb zvinhu zvakafanana neya mhangura, izvo zvinoita kuti zvinhu zvive neakanyanya kujeka kuenzana.

3.Panda PCB Kambani yakawedzera michina yekugadzira uye r & d yekudyara. Mumakore mashoma apfuura mumunda weHFB pcb kusimudzira, kune vatengi vanobva pasirese kusangana neRFBP yemusika mushambadziro, isu tine ruzivo rwakakura mukugadzirwa kwePTFE pcb yemabhodhi akasiyana-siyana eHF, anogona kukurumidza kuenda kumuenzaniso uye kugadzirwa kwehuwandu. Yedu huru teflon zvinhu vatengesi vanosanganisira: Rogers pcb, Nelco pcb, Taconic pcb, Arlon pcb.

General gwaro kuRF rakadhindwa redunhu mabhodhi

RF uye Mircowave pcb dhizaini

Yemazuva ano PCBS inosanganisa akasiyana-siyana edhijitari uye akavhenganiswa-chiratidzo matekinoroji, saka dhizaini uye dhizaini zvinowedzera kunetsa, kunyanya kana rf uye microwave zvasanganiswa kune zvidimbu-zvidimbu. Kunyangwe iwe uchishanda nesu, mumwe RF PCB mutengesi, kana kugadzira yako wega RF PCB, kune akati wandei ekufunga.

Chekutanga ndechekuti iyo RF frequency renji inowanzo kuve 500 MHz kusvika 2 GHz, asi magadzirirwo ari pamusoro pe100 MHz anowanzoonekwa seRF PCBS. Kana iwe ukashambadzira kupfuura 2 GHz, iwe uri mune microwave frequency renji.

RF uye microwave pcb magadzirirwo ane mamwe misiyano mikuru – mutsauko uripakati pavo neyakajairika dhijitari kana analogog wedunhu.

Muchidimbu, RF yakadhindwa wedunhu mabhodhi ari kushandisa analogo masaini pakukwirira kwakanyanya masikirwo. Yako yeRF chiratidzo inogona kunge ingangoita chero magetsi uye yazvino nhanho chero nguva munguva, sekureba sekunge iri pakati peako mashoma uye akanyanya maganho.

RF uye microwave akadhindwa wedunhu mabhodhi anotumira masaini panguva imwechete uye mukati meimwe frequency band. Mafirita eBandpass anoshandiswa kutumira masaini mu “bhendi rekufarira” uye kusefa chero masaini kunze kweiyo frequency renji. Iyo bhendi inogona kuve yakatetepa kana yakafara uye inogona kuparadzirwa neiyo yepamusoro-frequency inotakura.
