Hoʻopau Paʻa Coaxial (Dummy Load)

ʻO ka RF Coaxial Fixed Termination i kapa ʻia hoʻi ʻo Dummy Load he mea hana microwave passive single port i hoʻohana nui ʻia i nā kaapuni microwave a me nā lako microwave. ʻO kāna kumu nui ka omo ʻana i ka mana o ka alapine radio a i ʻole nā ​​​​ʻōnaehana microwave; A i ʻole ma ke ʻano he ukana dummy no nā antennas a me nā kikowaena transmitter. I kekahi mau hoʻāʻo RF, i mea e pale aku ai i ka hoʻohuli ʻana o ka hōʻailona a hoʻopilikia i nā hopena hoʻāʻo, ua hoʻopili ʻia i nā awa i hoʻohana ʻole ʻia e like me nā ukana kūlike e omo i ka ikehu awa. Hiki iā ia ke lawelawe ma ke ʻano he ukana dummy i ka loiloi ʻana i ka hana o ka ʻōnaehana ma o nā kikowaena simulated (e like me nā antennas).

Hoʻākoakoa ʻia nā ukana dummy mai nā mea hoʻohui, nā poho wela, a me nā ʻāpana resistor i kūkulu ʻia. Wahi a nā alapine like ʻole a me nā mana, ʻo nā mea hoʻohui maʻamau o nā ʻano e like me 2.92, SMA, N, DIN, 4.3-10, a pēlā aku.

Ua hoʻolālā ʻia ka radiator me nā ana hoʻoheheʻe wela e pili ana i nā koi hoʻoheheʻe wela o nā pae mana like ʻole. Hoʻohana ka chip i kūkulu ʻia i hoʻokahi chip a i ʻole nā ​​​​hui chip he nui e like me nā alapine like ʻole a me nā koi mana.
Loaʻa i nā huahana moʻo hoʻopau paʻa coaxial nā ʻano o ka laulā hana ākea, ka coefficient VSWR haʻahaʻa, ka mana kiʻekiʻe, ka liʻiliʻi, a ʻaʻole maʻalahi e puhi.

ʻO kā mākou hui ka mea nui e noiʻi, hana, a kūʻai aku i nā ukana dummy me ka pinepine kiʻekiʻe o 110G. E hoʻokipa i nā mea kūʻai aku e hana i nā kūʻai, hiki iā ʻoe ke hoʻokaʻaʻike aku i nā kūʻai aku e hoʻopilikino e like me kāu mau pono noi
