Gịnị bụ RF resistor?

Gịnị bụ resistor RF? N'ikwu ya n'ụzọ dị mfe, a na-akpọ resistor eji eme ihe na sistemụ nkwukọrịta RF microwave resistor RF.
Onye ọ bụla kwesịrị ịma maka ọkụ redio ugboro ugboro, nke bụ mkpụmkpụ maka ebili mmiri electromagnetic ugboro ugboro dị elu.
A na-akpọ ọkụ eletrik dị elu nke na-agbanwe ihe karịrị ugboro 10000 kwa sekọnd.
Resistor RF bụ ngwaọrụ na-anaghị arụ ọrụ nke nwere ike igbochi ụzọ redio frequency current. Ma gbanwee ike eletriki ka ọ bụrụ okpomọkụ ma ọ bụ ụdị ike ndị ọzọ, ebe unit nke ohms (Ω) bụ otu ihe ahụ dị ka resistor nkịtị.

A na-ekewa ihe mgbochi RF dabere na ike, enwerekwa ụzọ dị iche iche isi kewaa ha:

E kewara ya site na nhazi mpụga, enwere ike kewaa ya n'ime:

1. Chip Resistor (a na-ekewa resistor chip n'ime otu electrode chip resistor na dual electrode chip resistor)

2. Nguzogide nwere ndu (a na-ekewa nguzogide nwere ndu n'ime otu nguzogide nwere ndu na nguzogide nwere ndu abụọ)

3. Nguzogide Flanged (a na-ekewa ndị na-eguzogide flanged n'ime otu nguzogide flanged lead na nguzogide flanged abụọ)

 

Dịka nhazi usoro mmepụta si dị, enwere ike kewaa ya n'ime:

1. Ihe mkpuchi RF dị arọ (nke a na-akpọ ihe mkpuchi ihe nkiri dị arọ)

2. Ihe mkpuchi RF dị gịrịgịrị (a na-akpọ ya ihe mkpuchi fim dị gịrịgịrị)

 

Dịka nhazi ike si dị, enwere ike kewaa ya n'ime:

1. Nnukwu ike RF resistor (a na-akpọ ya nnukwu ike resistor, nke na-ezo aka na resistor nwere ike nke 60W ma ọ bụ karịa)

2.Njikwa RF dị ala (nke a kpọrọ "resistor dị ala", nke na-ezo aka na "resistor dị ala" n'okpuru 20W)

 

Kewara ya site na ugboro ole, enwere ike kewaa ya n'ime:

1. Nguzogide RF ugboro ugboro dị elu (a na-akpọ ya nguzogide ugboro ugboro dị elu, n'ozuzu ya nguzogide nwere ugboro ugboro dị elu karịa 3GHz)

2. Nguzogide RF ugboro ole na ole dị ala (a na-akpọ ya "resistor ugboro ole na ole", nke na-abụkarị resistor nke ugboro ole na-erughị 3GHz)

 

Ihe na uru na ọghọm dị na imepụta ihe mgbochi RF:

1. Beryllium oxide (BeO) nwere oke ike okpomọkụ, ihe fọrọ nke nta ka ọ bụrụ hà nhata ọla kọpa na aluminom dị ọcha, yana oke ike okpomọkụ nke 200-250W (mK), na-eme ka ọ bụrụ ihe kacha mma maka ime resistors RF. Ihe ọghọm kachasị na ya bụ na ọ na-egbu egbu nke ukwuu n'ụdị ntụ ntụ, na-eme ka ọ sie ike maka mmerụ ahụ kọntaktị ịgwọ. Ya mere, n'ozuzu, ndị na-emepụta resistors RF na-azụta ihe mpempe akwụkwọ a kpụrụ akpụ ma anaghị achọ nhazi nke abụọ. Nke a na-eme ka ojiji nke beryllium oxide (BeO) mee resistors RF nke enwere ike ibipụta naanị na otu mgbawa, na-ebelata arụmọrụ mmepụta nke ukwuu.

2. Aluminum nitride (AlN) bụkwa ihe nwere nnukwu ike okpomọkụ, yana ike okpomọkụ nke ihe dị ka 20W/mK. O nwere ezigbo ihe eji arụ ọrụ ma nwee ike ịgbatị ahụ karịa aluminum oxide na seramiiki beryllium oxide. N'ihi na ọ naghị egbu egbu, enwere ike ibipụta ya site na iji teknụzụ mbipụta na-aga n'ihu, nke nwere ike ime ka arụmọrụ mmepụta dịkwuo mma. Ugbu a, ọ bụ ihe a na-ahọrọ maka resistors RF dị ike.

3. Aluminum oxide (Al2O3) bụ ihe a na-ahọrọ maka resistors elu dị ala, ebe ọ bụ na conductivity okpomọkụ ya dị ihe dị ka 1/5 nke aluminum nitride. A naghị eji ya eme ihe mgbe niile n'ịhọrọ ihe maka resistors RF dị elu.
