Dhizaini Yedu Yekugadzira Duplexer/Diplexer yeRF Solutions

Tsananguro yeChigadzirwa

MaDiplexer/Duplexer edu akagadzirwa nemaoko iRF filters dzinokosha mukushandiswa kwemafrequency akakwira uye dzakagadzirirwa kusangana nezvinodiwa zvakasiyana-siyana zvekutaurirana. Mafrequency anosvika 10MHz kusvika 67.5GHz, zvichiita kuti zvive nyore kushanda munzvimbo dzakasiyana-siyana dzekushandisa. Ingave mukutaurirana kusina waya, kutaurirana nesatellite kana mimwe minda yekugadzirisa masaini akakwira, zvigadzirwa zvedu zvinogona kupa mhinduro dzakavimbika.

Basa guru re duplexer nderekuparadzira masaini kubva pachiteshi chimwe chete kuenda kunzira dzakawanda kuitira kuti zviratidzo zvifambiswe zvakanaka. Ma duplexer edu ane kurasikirwa kwakaderera kwekupinza, kupatsanurwa kwakanyanya uye kugona kubata simba rakawanda, izvo zvinogona kuderedza kurasikirwa kwechiratidzo zvinobudirira uye kuvandudza mashandiro ese ehurongwa. Hunhu hwakaderera hwePIM (intermodulation distortion) hunoita kuti zvigadzirwa zvedu zvishande zvakanaka mukushandiswa kwesimba rakawanda, zvichiita kuti masaini ajeke uye agare akasimba.

Panyaya yekugadzira, maduplexer edu anoshandisa matekinoroji akasiyana-siyana epamusoro, anosanganisira cavity, LC circuit, ceramic, dielectric, microstrip, spiral uye waveguide, nezvimwewo. Kusanganiswa kwetekinoroji idzi kunoita kuti zvigadzirwa zvedu zvive zvinochinjika zvakanyanya muhukuru, huremu uye mashandiro. Tinopawo masevhisi ekugadzira zvinhu kuti tisangane nezvinodiwa nevatengi vedu maererano nehukuru uye zvinodiwa zvehunyanzvi, tichiona kuti duplexer yega yega yakakodzera zvakakwana nzvimbo yayo yekushandisa.

Pamusoro pezvo, maduplexer edu haapindi mukudengenyeka kana kuvhunduka, zvichivabvumira kushanda zvakavimbika munzvimbo dzakaoma. Panguva imwe chete, dhizaini isingapindi mvura inoitawo kuti zvigadzirwa zvedu zvikodzere nzvimbo dzekunze nedzimwe dzine hunyoro, zvichiwedzera mukana wekushandiswa kwadzo.

Muchidimbu, ma duplexer/dividers akagadzirwa neApex haangoshande zvakanaka chete asi anosanganawo nezvinodiwa zvakasiyana-siyana zvemasystem ekutaurirana emazuva ano maererano nekuvimbika uye kuchinjika. Kunyangwe uchida mhinduro yeRF inoshanda zvakanyanya kana dhizaini chaiyo, tinogona kukupa sarudzo yakanakisa.
