Kugadzira PCB yeFirita yeTMM4

Kugadzirwa kwePCB yeTMM4 firita kunodzorwa ne geometry inogadzirisa mhinduro yefirita. Saka maResonator, mitsetse yakabatana, makomba uye machinjiko akaputirwa anofanira kusunungurwa nehukuru hwakajeka uye kushivirira. TMM4 inonyanya kubatsira kana microwave circuit ichifanira kuva diki pasina kuenda pakarepo kune substrate yakanyanya-Dk. Izvi zvinoita kuti ive chinhu chinoshanda chemafirita madiki, maResonator, maCouplers, ma matching network uye maRF modules ane nzvimbo uko centre frequency uye coupling zvinoenderana nehukuru hwakapedzwa. Kana paine dielectric constant yakasiyana, TMM6 filter construction senzira yakasiyana inoda RF model yakagadziriswazve pane kutsiva zvinhu chete.

Highleap Electronics inogadzira maPCB eTMM4 kubva kumaprototypes akagadziridzwa kuti adzokorore kugadzirwa. Basa iri rinotarisa pahukuru hunoisa mhinduro yeRF, mashandiro uye kupedzisa kunodiwa nemodule, uye humbowo hunodiwa usati waburitsa volume.

Peji reTMM4 rine michina yekugadzira mafirita ema microwave. Zviyero zveResonator, ma coupling structures, plated transitions uye first-article RF measurements zvinoonekwa sezvinhu zvikuru zvinodzora kugadzirwa kwete kudzokorora ruzivo rwezvinhu zveTMM.

Nei TMM4 Inoshandiswa paCompact Microwave Filter PCB

TMM4 ine nzvimbo yepakati: inopfupisa zvivakwa zvakapararira zvichienzaniswa neTMM3 uku ichichengetedza mitsetse yakawanda nemaburi anogadzirwa kupfuura zvinhu zveDK zvakanyanya. Chirongwa ichi chinofanira kutsanangura kuti kuderedzwa kwehukuru kwakadii kunodiwa, nekuti kuderedzwa kwega kwega kunowedzera huwandu hwemhedzisiro yekushanduka kwe etch, ukobvu uye kusiyana kwedzimba.

Mafirita nemakoupler zvinodzorwa ne geometry yakapedzwa

Chinyorwa che "generic impedance note" hachina kukwana pa "narrowband filter". Kureba kwe "resonator", "coupling gap", nzvimbo yakavhurika, kuburikidza nemadziro nenzvimbo ye "housing space" zvinogona kudzora zvakananga frequency yepakati, bandwidth uye kurambwa. Mufananidzo unofanirwa kuratidza zviyero izvi uye kutaura kana "final plating" uye "finish" zvakabatanidzwa.

Chimiro chezvinhu: Peji rino rine chekuita nekugadzirwa kwePCB uchishandisa zvinhu zvakatarwa zveRogers. Highleap Electronics inogadzira bhodhi rakapedzwa nePCBA; kugadzirwa kwelaminate uye kutengeswa kwezvinhu zviri kunze kwechikamu chedu chebasa.

Kubva paSimulation kuenda kuPrototype yeTMM4 Yakagadziriswa

Muenzaniso wekutanga unofanirwa kugadzirwa senzira yekudzidza, kwete kungotevedzera murayiro wekupasa/kukundikana. Highleap inogona kuyera zviyero zvakakosha zvakabvumiranwa uye kupa zvinyorwa zvekugadzira kuitira kuti mutengi azvienzanise nemhinduro yeRF yakaedzwa uye yakayerwa. Kana paine maturusi ekugadzirisa kana magadzirirwo ekugadzirisa, nzira yekugadzirisa inofanira kudzokororwa zvakakwana kuti igadziriswe.

Machining, maburi uye maburi akaiswa

Mamodule eTMM4 anowanzo shandisa makomba akarongwa, zvinhu zvekuisa, makomba akarongwa kana simbi inotsigirwa. Zvinhu zvemakanika zvinofanirwa kuratidza datum system yakafanana nemifananidzo yekusefa. Kuisa makomba uye mhando yemupendero zvinonyanya kukosha kana mavias achigadzira madziro ekudzivirira kana kuti chinongedzo chekubatanidza chiri pedyo nemuganhu wakarongwa.

Kusunga waya uye kupedzisa kwakasarudzwa

Nzvimbo dzine waya kana dzinosungirirwa nesimbi hadzifanirwe kuwana magumo asina kutaurwa. Kugadzirwa kwesimbi, ukobvu, kubviswa kwemasiki uye kuchena zvinofanirwa kuenderana nemaitiro ekugadzira. Highleap inogona kuronga magumo asina bhodhi nezvinodiwa zvekugadzira PCB kana module yacho yapihwa sePCBA yakazara.

Kugadzira Module Dzine Dzimba uye Dzine Simba reTMM4

Chitsigiro chesimbi kana imba yakagadzirwa nemuchina zvinogona kupa kupararira kwekupisa, kuomarara uye kudzivirira RF, asi zvinoshandurawo nharaunda yemagetsi. Ukobvu hwenamira, nzvimbo yesikuruu, kudzika kwegomba uye nzvimbo yekuparadzanisa chivharo zvinofanirwa kuiswa mukusimbisa. Bhodhi rinopfuura munzvimbo yakasununguka rinogona kuchinjika kana rabatanidzwa muchikamu chekupedzisira.

Kuti uwane dhizaini yakakura uye mamiriro ekugadzira, ona matekiniki eRF PCB miniaturization.

Kufambisa Firita yeTMM4 Kubva paPrototype kuenda kuVhoriyamu

Kugadzirira huwandu hwevhoriyamu kunoratidzwa kana mhinduro yeRF inogamuchirwa ichigona kubatanidzwa kune zvinoyerwa kugadzirwa. Highleap inogona kuchengetedza stackup yakatenderwa, kuvakwa kwezvinhu, manotsi ekushandisa, mushumo wehukuru hwakakosha uye zvinodiwa zvekuyedza zvekudzokorora maodha. Kana shanduko yezvinhu, mhangura kana finish ikakurudzirwa, inofanira kuongororwa isati yagadzirwa nekuti mhinduro inogona kufamba.

Humbowo hwekugadzira

Chirongwa chekugadzira chinogona kusanganisira kuongorora zvinhu zviri kuuya, kubhadhariswa kwe etch inodzorwa, kuongororwa kwemaziso, microsection, bvunzo yemagetsi uye bvunzo yeRF yakatsanangurwa nevatengi. Prototype uye maodha e low-volume anogona kuteverwa ne component sourcing uye module assembly uko BOM, placement uye functional limit zviripo. Highleap inoongorora chimiro chefirita, machining, plated holes uye reference-plane relationships isati yasvika nyaya yekutanga. Kana zvichitarisirwa kugadziriswa, prototype plan inofanira kutaura kuti ndeapi masayizi anogona kugadziriswa uye ndeapi anogadziriswa ne production draw. Makoshero chaiwo epfuma yezvinhu anofanira kuongororwa zvichienderana nemagwaro emutengesi aripo egiredhi rakatarwa uye kuvaka. Kune nzira yekugadzira ye lower-Dk, TMM3 RF-module construction inopa shanduko yakasiyana ye geometry iyo inofanira kuongororwa isati yaoma stackup.

Mibvunzo yesefa yeTMM4

TMM4 inogara iri nani pane TMM3 here? Kwete. TMM4 inopa miniaturization yakawanda, nepo TMM3 inogona kupa hunyanzvi hwakakura uye mukana wekuwedzera webroadband.

Sefa inofanira kugamuchirwa ne impedance coupon here? Kazhinji kwete ne coupon chete. Mhinduro ye sefa uye zviyero zvakakosha zvingave zvakakosha. Kune quote ye sefa yeTMM4, ipai marongerwo e sefa, frequency band, stackup, zviyero zvakakosha, finish uye huwandu. Isai nzira yekuyera RF inodiwa kana sefa yagamuchirwa nemhinduro yakayerwa.
