Nheyo uye Mashandisirwo e3-Port Circulator muMicrowave System

Nzvimbo ye3Circulatormudziyo unokosha we microwave/RF, unoshandiswa zvakanyanya mukutumira masaini, kupatsanura uye muzviitiko zviviri. Chinyorwa chino chinosuma muchidimbu musimboti wechigadzirwa chayo, hunhu hwekushanda kwayo uye mashandisirwo akajairika.

Chii chinonzi 3-portcirculator?

Nzvimbo ine chiteshi chezvitatucirculatorchishandiso chine madoko matatu chisingapindi, uye chiratidzo chinogona kungotenderera pakati pemadoko nenzira yakatarwa:

Kupinza kubva pachiteshi 1 → kubuda kubva pachiteshi 2 chete;

Kupinza kubva pachiteshi 2 → kubuda kubva pachiteshi 3 chete;

Kupinza kubva pachiteshi 3 → kubuda kubva pachiteshi 1 chete.

Zvakanaka, kutumira chiratidzo che3-portcirculatorinotevera gwara rakatarwa: chiteshi 1 → chiteshi 2, chiteshi 2 → chiteshi 3, chiteshi 3 → chiteshi 1, zvichigadzira nzira yerukoko rwekutenderera. Chiteshi chimwe nechimwe chinotumira masaini kune chimwe chiteshi chete, uye chiratidzo hachizotumirwe nekumashure kana kubuda mvura kune mamwe machiteshi. Hunhu uhwu hunonzi "kusawirirana". Maitiro aya ekutumira anogona kutsanangurwa ne standard scattering matrix, zvichiratidza kuti ine kurasikirwa kwakaderera kwekupinza, kupatsanurwa kwakanyanya, uye mashandiro ekutumira akananga.

Maitiro Akajairika

Kushandiswa kweIsolator: Inowanzoshandiswa muma microwave ane simba guru kudzivirira ma transmitter kubva mukukuvadzwa kwemafungu. Chiteshi chechitatu chakabatana nemutoro unoenderana kuti chiwane kuparadzaniswa kwakanyanya.

Basa reDuplexer: Mu radar kana masisitimu ekutaurirana, inoshandiswa kuti ma transmitters nema receiver vagovane antenna imwe chete pasina kukanganisana.

Sisitimu yeReflection Amplifier: Pamwe chete nemidziyo yekudzivirira simba (yakadai seGunn diodes), macirculator anogona kushandiswa kupatsanura nzira dzekupinda nedzekubuda nadzo.
