Iyo Yekupedzisira Inotungamira kune Microwave PCB Dhizaini

Dhizaini yeMicrowave PCB inzvimbo yakakosha yekushandiswa kwemasekete emagetsi ane frequency yakakura, inoda kunzwisisa kwakadzama kwemitemo yemagetsi uye mainjiniya chaiwo kuti isangane nezvinodiwa zvemashandisirwo emazuva ano, akaomarara. Dhizaini yemasekete emicrowave inosanganisira matambudziko akati wandei asingawanzo sanganisirwe mumagadzirirwo ePCB ane frequency yakaderera . Matambudziko aya anosanganisira kusimba kwechiratidzo chekumhanya kwakanyanya, kudzora impedance, kufunga nezvezvinhu, uye kunyatsogadzirwa. Pazasi pane kuongororwa kwakadzama kwematambudziko makuru mudhizaini yePCB yemicrowave uye matekiniki anoshandiswa kugadzirisa iwo. Kune masekete emicrowave akavakirwa paRO3035 , shandisa ukobvu hwakasarudzwa hwelaminate uye kushivirira kwekugadzira paunenge uchishandura modhi yeRF kuita hunyanzvi hwekugadzira.

1. Matambudziko Akakosha muMicrowave PCB Dhizaini

Ma microwave PCB anowanzo shandiswa mumapurogiramu anoshanda pama frequency ari pamusoro pe 1 GHz, kazhinji achipfuura 30 GHz mune mamwe masisitimu. Aya masaini ane frequency yakakwira anoratidza hunhu hwakasiyana hunoda matekiniki ekugadzira akasarudzika. Kunzwisisa matambudziko aya kwakakosha pakuona kushanda, kuvimbika, uye kugona kugadzirwa kwema microwave PCB.

Makiyi Dhizaini Matambudziko:

• Kugadzikana kweWave Impedance : Kuwana nekuchengetedza impedance yakajairika muPCB stackup kwakakosha pamashandisirwo ehigh-frequency. Chinodiwa chenguva dzose kuchengetedza impedance ye50Ω ine kutsungirira kwe±5%, kunyanya mumagadzirirwo e multi-layer uko kusawirirana kwempedance kunogona kutungamira kukuratidzira kwechiratidzo uye kurasikirwa nesimba.

• Kupararira kweDielectric : Pamafrequencies akakwira, dielectric constant (Dk) yezvinhu zvinosiyana zvichienderana nefrequency. Semuenzaniso, substrates dzakadai selaminate yakasarudzika ine low-loss loss ine DC ye3.48±0.05 pa10GHz, izvo zvinoda kutevedzera kwakanyatsonaka kuti uverenge maitiro anoenderana nefrequency. Kuchinja uku kunogona kukonzera kunonoka kwesignal, phase shifts, uye reflections kana zvisina kugadziriswa nemazvo.

• Kukanganiswa Kwekuoma Kwepamusoro : Kuoma kwemavara emhangura kunogona kukanganisa zvakanyanya kurasikirwa kwekuisa uye kusimba kwechiratidzo, kunyanya pamafrequency akakwira. Semuenzaniso, kuoma kwemhangura kwe0.4μm kunogona kukonzera kurasikirwa kwekuisa kwe0.15 dB/inch pa40GHz. Kuti vadzikise mhedzisiro yakadaro, vagadziri vanofanirwa kudzora magadzirirwo epamusoro pemhangura uye kushandisa matekiniki akadai sekuisa mhangura yakatsetseka.

• Kuburikidza neStub Resonance : Ma "Via stubs" anogona kugadzira ma "resonant frequency" asingadiwe ayo anovhiringidza nzira ye "signal". Dambudziko rinowanzoitika kana "via stubs" ikatanga kurira pama "frequency" akadai se28GHz (λ/4 via stubs), zvichikonzera 0.3dB null points mu "signal transmission". Matekiniki ekudhonza ma "back-drilling" anoshandiswa kuderedza ma "stubs", ne "tight positional accuracy" asingasviki 50μm kuti pave nemhedzisiro yakanaka.
