Ma Waveguide Manual Phase Shifters ndi zida zongogwiritsidwa ntchito pokonza ma RF ndi ma microwave zomwe zimatha kusintha gawo la chizindikiro pamanja. Ndi zofunika kwambiri pakugwiritsa ntchito komwe kumafuna kuwongolera bwino gawo la chizindikiro.

Cholinga:

1. Kusintha kwa Gawo: Chosinthira gawo la microwave chimagwiritsidwa ntchito kusintha gawo la chizindikiro pamanja kuti chikwaniritse kulamulira kwa gawo molondola. Izi ndizofunikira kwambiri pakufananiza gawo ndi kusintha kwa gawo.
2. Kubwezera Gawo: Ma Millimeter wave phase shifters amagwiritsidwa ntchito kubwezera cholakwika cha gawo mu dongosolo ndikuwonetsetsa kuti gawo la chizindikiro panjira zosiyanasiyana likugwirizana, motero kukonza magwiridwe antchito a dongosolo.
3. Kupanga Beamforming: Mwa kusintha gawo la antenna iliyonse mu gulu la antenna, chosinthira ma radio frequency phase chingathe kupanga beamforming ndi beam scanning.
4. Kufananiza Magawo: Mu machitidwe a njira zambiri, ma shifter a gawo la mm-wave amagwiritsidwa ntchito kuti atsimikizire kuti magawo a njira iliyonse akugwirizana, motero kukwaniritsa kufanana kwa magawo.

Ntchito:

Chosinthira gawo la RF chili ndi ntchito zosiyanasiyana pakulankhulana kwamagetsi, ndipo chimodzi mwa ntchito zake zazikulu ndi kuwerengera gawo.
1. Mu machitidwe olumikizirana, ma phase shifters angagwiritsidwe ntchito kulumikiza ma signali ochokera ku magwero osiyanasiyana a signali kapena njira kuti atsimikizire kuti afika kumapeto kolandirira ndi gawo loyenera. Mwa kusintha gawo la chizindikiro cholowera, phase shifter imakwaniritsa zofunikira pakulinganiza gawo, potero imawongolera magwiridwe antchito ndi kukhazikika kwa dongosolo.
2. Magawo osinthira amagwiritsidwa ntchito kwambiri mu njira zosinthira ndi kuchotsera kuti asinthe gawo la zizindikiro zonyamulira, kuti akwaniritse kuchotsera chizindikiro ndi kuzindikira njira zosiyanasiyana zosinthira (monga PSK, QAM, ndi zina zotero).
3. Ponena za kupanga ma frequency, ma radio frequency phase shifters angagwiritsidwe ntchito kusintha gawo la ma signals pama frequency osiyanasiyana, potero kukwaniritsa cholinga cha kupanga ma frequency.
4. Kulankhulana kwa digito: Bidi.

Izi zimagwira ntchito yofunika kwambiri m'magawo monga kulankhulana opanda zingwe ndi machitidwe a radar.

Qualwaveimapereka ma Waveguide Manual Phase Shifters kuchokera pa 3.22 mpaka 12.4GHz. Kusintha kwa gawo kumafika pa 360°/GHz.
