Zvidziviriri Zvinochinja-chinja zveWaveguide

Muma microwave circuits, simba remasaini rinowanzova rakakwirira kwazvo. Kana simba rakawandisa risingakwanise kudzorwa zvizere, rinokonzera matambudziko akawanda mu circuit, akadai sekupfuura simba rakawanda rezvikamu zve circuit uye kukonzera kutsauka kwakasiyana-siyana. Kushandiswa kwema waveguide variable attenuators kunogona kusangana nezvinodiwa zvekuderedza simba remasaini uye kuve nechokwadi chekuti ma microwave circuits anoshanda zvakanaka.
Pfungwa yekushanda kwe "continuously variable attenuator" inobva pahunhu hwe "propagation" hwe "electromagnetic waves" muma "waveguides". Inonyanya kusanganisira ma "waveguides", "impedance matching devices", uye "variable conductor blocks". Kana chiratidzo chikapfuura nemu "waveguides", chikamu chesimba chinotorwa ne "conductor block", nokudaro zvichideredza simba re "signal".
Kana bhokisi remuchina riri chimiro chemuchina chinogona kugadziriswa nemaoko nemushandisi, ianodzivirira anotenderera. Anodzivirira anoshanduka nemaoko anobatsira zvikuru muhurongwa hwekutaurirana kwemagetsi.

Kushandiswa:

1. Kuti ive nechokwadi chekuti mwero wezviratidzo uri pakati nepakati, ma "waveguide variable attenuators" anogona kuwanikwa nekuderedza simba rezviratidzo.
2. Kuwedzera simba remuchina uyu zvakare chinhu chakakosha pachinhu chinotenderedza chinobata masimbi, icho chinogona kuona kuti muchina uyu unoshanda zvakanaka.
3. Kuenzanisa impedance kunogona kudzivirira kuratidzwa kwechiratidzo uye kurasikirwa, zvichiita kuti chiratidzo chigare chakasimba.

Chinovhara mafungu chinoshandiswa zvakanyanya mukutaurirana kwe microwave uye mukuyedza murabhoritari. Chinogona kushandiswa kugadzirisa simba remasaini kuti rienderane nezvinodiwa zvakasiyana. Semuenzaniso, murabhoritari, danho rinotenderera rinogona kupa kugona kwekugadzirisa kunochinjika kana simba remasaini richida kuchinjwa kuti riedze mashandiro emidziyo. Mukutaurirana kwe microwave, zvinodzivirira mafungu zvinochinjika zvinochinjika zvinogona kushandiswa kugadzirisa simba remasaini kuti ive nechokwadi chekuti chiratidzo hachina kusimba zvakanyanya kana kushata zvakanyanya panguva yekutumira.
Zvakanakira zvevariable attenuators ndezvekureruka, nyore kushandisa, uye kugadziriswa kunochinjika. Nekushandisa nemaoko, vashandisi vanogona kudzora zvakakwana huwandu hwesignali inodzikiswa sezvinodiwa. Zvisinei, kana tichienzanisa neautomatic waveguide attenuators, huwandu hwekugadzirisa hwema waveguide attenuators emaoko hunogona kunge hwakati diki, uye maitiro ekugadzirisa anoda nguva yakati uye kururama.

Qualwaveinopa VSWR yakaderera uye kupfava kwakanyanya kubva pa0.96 kusvika 500GHz. Kupfava kwakanyanya kuri 0~40dB.
