RF coaxial connectors yɛ ɛlɛtrɔnik nneɛma a ɛho hia a wɔde di dwuma de kɔma high-frequency signals. Wɔn adwuma titiriw ne sɛ wɔbɛma anyinam ahoɔden nkitahodi a wotumi de ho to so wɔ mfiri ahorow ntam bere a wɔkora sɛnkyerɛnne no mudi mu kura so no. Wɔn nhyehyeɛ no nya nkɛntɛnsoɔ tẽẽ wɔ transmission adwumayɛ so na titire no ɛka nneɛma titire te sɛ emu conductor, akyi conductor, dielectric support, ne akyi dan.
Mpɛn pii no, wɔde kɔbere a wɔde afra (te sɛ beryllium kɔbere anaa phosphor kɔbere) na ɛyɛ ntini a ɛwɔ mu, a ɛyɛ nkitahodi no fã a ɛma nsu fa mu no mfinimfini na wɔde sika kɔkɔɔ anaa dwetɛ akata so na ama nsu a ɛkɔ mu no ayɛ kɛse na ɛko tia nsɛe. Pɛpɛɛpɛ a emu conductor no nya sɛnkyerɛnne kwan so nkrasɛm so nkɛntɛnso tẽẽ, enti ɛsɛ sɛ wɔhwɛ ne dimensional tolerances ne surface finish so katee.
Mpɛn pii no, wɔde kɔbere a wɔde afra anaa dade a ɛnyɛ den na ɛyɛ akyi conductor a ɛyɛ kyɛm no na wɔde nso kata so ma ɛko tia oxidation kɛse. Abɔnten conductor no adwuma titiriw ne sɛ ɛbɛtew electromagnetic interference (EMI) so na abɔ sɛnkyerɛnne no ho ban afi abɔnten dede ho bere a wɔde rekɔma no. Ɛtaa de nhama anaa bayonet nkitahodi di dwuma na ama wɔanya mfiri a wɔde ka bom a ahobammɔ wom.
Dielectric support a ɛwɔ mu ne akyi conductors ntam no, wɔtaa de nneɛma a ɛyera pii te sɛ polytetrafluoroethylene (PTFE), ceramic, anaa polyethylene na ɛyɛ. Ɛnyɛ sɛ dielectric mmoa no bɔ gyinabea a ɛwɔ mu no ho ban nko na mmom ɛkyerɛ nkitahodi no impedance su (sɛ nhwɛso no, 50Ω anaa 75Ω), na ɛnam so nya sɛnkyerɛnne a wɔde fa so no so nkɛntɛnso.
Ɔdan no ma mfiri ahobammɔ ne nneɛma a atwa yɛn ho ahyia nsɔano na wɔtaa de aluminium aduru anaa dade a ɛnyɛ den na ɛyɛ, anodized anaasɛ plated ma ɛyɛ den. Ɛsɛ sɛ dan no nhyehyɛe nso susuw sɛnea ɛbɛyɛ mmerɛw sɛ wɔde bɛhyɛ mu na woayi afi hɔ ne sɛnea ɛne nneɛma a atwa yɛn ho ahyia hyia te sɛ nsu a wɔde siw ano ne mfutuma a wɔde siw ano no ho.
Bio nso, ɛsɛ sɛ RF coaxial connectors no nhyehyɛɛ susuw nneɛma te sɛ contact resistance, voltage standing wave ratio (VSWR), ne mfiridwuma nkwa ho na ama wɔahwɛ ahu sɛ ɛbɛgyina pintinn na wotumi de ho to so wɔ high-frequency applications mu. Ɛdenam nneɛma ne akwan a wɔfa so yɛ ade biara a wɔyɛ no yiye so no, nnɛyi RF coaxial nkitahodi ahorow no di mfiridwuma mu ahwehwɛde ahorow a ɛwɔ dwumadie a ɛkorɔn-awieɛ ho dwuma, ɛfiri nkitahodiɛ mfiri so kɔsi ahunmu.
