MaBaluns eRF epamusoro pegomo reMikrowevu, Millimeter Wave mm wave
MaSurface Mount Baluns (Balance-Unbalance transformers) imhando dzeRF/microwave dzakagadzirirwa kushandura masaini emagetsi akaenzana uye asina kuenzana mumasekete emagetsi ane mafrequency akakwira. Zvichigadzirwa uchishandisa matekinoroji epamusoro e thin-film kana multilayer ceramic, zvishandiso izvi zvine compact zvinopa shanduko yakakosha ye impedance uye kugona kurambwa kwe common-mode. Sezvinhu zvakakosha musystem dzisina waya, zvinoita kuti masaini ave akachengeteka zvakanaka uku zvichitevedzera maitiro emazuva ano ekugadzira otomatiki. Dhizaini yavo yekuisa pamusoro inoita kuti ive yakakodzera kugadzirwa kwepamusoro-soro mumafoni, IoT, uye maapplication emagetsi evatengi.
Zvinhu Zvikuru uye Hunhu:
1. Kushanda kwepamusoro-soro uye mainjiniya chaiwo
Kushanda kweBroadband: Kutsigira mafrequency akasiyana-siyana (kubva kuMHz dzakawanda kusvika kumulti-GHz bands) nekushanda kwakafanana mumabandwidths akatarwa, zvichibvisa kudiwa kwezvikamu zvakawanda zveband narrowband.
Kuchinja kweimpedance kwakarurama: Ipa zviyero zvekushandura kweimpedance zvakarurama (semuenzaniso, 1:1, 1:4, 4:1) zvine kutsungirira kwakasimba (± 5% yakajairika) kuti zvienderane nezvinodiwa zvesystem zvakasiyana uye zvinogumira padanho rimwe chete.
Kuenzanisa kwakanaka kwe amplitude/phase: Chengetedza amplitude balance yepamusoro (kazhinji ± 0.5 dB) uye phase balance (kazhinji ± 5 degrees) kuti ruzha rwe common-mode rurambe zvakanaka.
Kurasikirwa kwakaderera kwekupinza: Wana kurasikirwa kushoma kwechiratidzo (kusvika pa0.5 dB zvichienderana nehuwandu) kuburikidza nekubatanidza kwakagadziridzwa kwemagineti uye zvinhu zve dielectric zvinorasikirwa zvishoma.
2. Kugona kwepamusoro kurongedza nekubatanidza
Zvinhu zvine chimiro chakabatana: Zvinowanikwa mumapakeji akajairika eindasitiri uye saizi dzakagadzirirwa magadzirirwo asina nzvimbo yakawanda.
Kuenderana kwenzvimbo: Kunoenderana nemidziyo yekusarudza-uye-nzvimbo otomatiki uye maitiro ekugadzirisazve soldering, zvichigonesa kugadzirwa kwepamusoro-soro.
Kuvaka kwakasimba: Shandisa ceramic, ferrite, kana composite substrates dzine termination finishes (Ni/Sn, Au) dzakakodzera mamiriro ekunze akaoma.
ESD nekudzivirira kupisa: Zvishandiso zvekudzivirira zvakabatanidzwa zvinotsungirira zviitiko zveESD (kusvika 2kV HBM) uye tembiricha yekushanda.
3. Kuvimbika kwakavandudzwa uye kugadziriswa kwezvishandiso zvakanangana nezvinodiwa
Kushanda kwakanyanya kwekuparadzanisa: Ipa kupatsanurwa kwechiteshi kubva kune chimwe chinhu kuenda kune chimwe chinhu kunowanzo pfuura 20 dB kudzivirira kubatana kwechiratidzo kusingadiwe.
Kugona kubata simba: Kutsigira mazinga esimba kubva pa milliwatts kusvika pa watts dzakawanda zvichienderana nehukuru hwepakeji uye dhizaini.
Kugadziriswa kwemhando dzakasiyana: Kunowanikwa mumagadzirirwo akagadzirirwa maapplication chaiwo (Wi-Fi, nharembozha, Bluetooth, nezvimwewo) ane maS-parameters akasiyana.
Mashandisirwo:
1. Masisitimu ekutaurirana asina waya
Zvivakwa zvemafoni: Matransceiver epachiteshi chepasi, masisitimu makuru eMIMO, uye masero madiki anoda kuenderana ne impedance uye kurambwa kwe common-mode muRF front-ends.
Mamodule eWi-Fi/Bluetooth: Batidza kubatana kweantenna dzakasiyana uye kuvandudza kunzwisiswa kwevanogamuchira mumabhendi efrequency e2.4/5/6 GHz.
Midziyo ye5G NR: Kurerutsira kugadziriswa kwemasaini e mmWave ne sub-6 GHz mumidziyo yemushandisi nezvivakwa zve network.
2. Zvishandiso zvemagetsi zvevatengi neIoT
Mafoni/Mapiritsi: Shandisa dhizaini yechikamu cheRF chakamanikana nekuvandudzika kwemasaini efoni, Wi-Fi, uye GPS receiver.
Zvigadzirwa zvemagetsi zvinopfekwa: Ipa mhinduro dzekuchinja zviratidzo zvidiki zvekutarisa hutano uye mamodule ekubatanidza.
Midziyo yepamba yakangwara: Inotsigira kubatana kwewaya isina waya mumasensa eIoT, mahubhu, uye macontroller anoda mashandiro eRF akavimbika.
3. Midziyo yekuyedza nekuyera
Vector network analyzers: Inoshanda sezvikamu zve calibration uye test fixtures kuti pave nekuyera kwakarurama kwekusiyanisa.
Vayedzisi vasina waya: Bvumira kuyedzwa kwechiteshi kwakaringana kwema amplifiers, mafirita, nezvimwe zvikamu zveRF
Masisitimu ekuvimbika kwechiratidzo: Anotsigira kuyedzwa kwedhijitari nekukurumidza kunosanganisira kusaina kwakasiyana (SerDes, PCIe, nezvimwewo).
4. Zvigadzirwa zvemagetsi zvemotokari nemaindasitiri
Masisitimu eV2X: Anotsigira mashandisirwo ekutaurirana kwenguva pfupi (DSRC) uye nharembozha-V2X (C-V2X).
IoT yeMaindasitiri: Ita kuti kubatana kwakasimba kwewaya kusina waya kuvepo mukugadzira otomatiki uye masisitimu ekutarisa ari kure.
Zvikamu zveTelematics: Zvinopa shanduko yeRF yakavimbika yemamodule ekutaurirana eGPS, cellular, uye satellite.
5. Zvigadzirwa zvemagetsi zvemuchadenga nezvokudzivirira
Masisitimu eAvionics: Anotsigira michina yekutaurirana, yekufambisa, uye yekutarisa ichizadzisa zvinodiwa zvakanyanya zvezvakatipoteredza.
Kutaurirana kwemauto: Ita kuti zvisungo zvisina waya zvive zvakachengeteka mumasisitimu anotakurika vanhu uye anoiswa mumotokari.
Masisitimu eRadar: Kubatsira kushandurwa kwakaringana/kusina kuenzana mumashandisirwo eradar ane zvikamu uye ekutevera.
Qualwaveinopa mabarani epamusoro ane mhando dzakasiyana kuti agutse zvinodiwa nevatengi.
