Mndandanda Wathunthu wa Terminology to High Power Transmitter Combiners
Nawa mawu ena owonjezera okhudzana ndi zophatikizira zamagetsi zapamwamba komanso mafotokozedwe awo:

1. Chiwerengero cha Mabowo: Chiwerengero cha zibowo mu chophatikizira chimatanthawuza kuchuluka kwa ma cavities ozungulira mkati mwa chophatikiza. Pabowo lililonse limapangidwa kuti lizigwira ntchito ngati dera lolumikizana lomwe limagwirizanitsa mphamvu kuchokera pazolowera kupita kudoko lophatikizira. Mphamvu yogwiritsira ntchito mphamvu ndi kudzipatula kwa chophatikizira kumawonjezeka ndi kuchuluka kwa ma cavities.

2. pafupipafupi: Kuchuluka kwa chophatikizira kumawonetsa gulu la pafupipafupi la cholumikizira. Pali ma frequency osiyanasiyana amitundu yosiyanasiyana yowulutsira, monga UHF (Ultra High Frequency), VHF (Very High Frequency), FM (Frequency Modulation), TV, ndi L-band. Frequency band imatsimikizira kuchuluka kwa ma frequency omwe ophatikiza angagwire.

3. Mphamvu Zolowetsa: Mphamvu yolowetsa imatanthawuza mphamvu yayikulu kwambiri yomwe chophatikizira chingathe kuchita popanda kuwonongeka kulikonse. Mphamvu yolowetsayo nthawi zambiri imawonetsedwa mu kilowatts (kW) ndipo ikuwonetsa mphamvu yayikulu yomwe wophatikizayo angapirire.

4. Kusintha: Pali mitundu yosiyanasiyana ya masinthidwe ophatikizira ma transmitter amphamvu kwambiri, kuphatikiza nyenyezi-point, CIB (Close-Input Band), ndi Stretchline. Kukonzekera kumatanthawuza momwe zizindikiro zolowera zimaphatikizidwira pamodzi ndi momwe zimagawidwira ku madoko otuluka a chophatikiza.

5. Mafupipafupi kapena Kutalikirana kwa Channel: Kutalikirana kwa ma frequency kapena kwachannel kumatanthauzidwa ngati kusiyana kocheperako pakati pa mayendedwe awiri oyandikana. Izi ndizofunikira pakupanga kophatikiza kuti muchepetse kusokoneza kwa intermodulation (IMD).

6. Kutayika Kwawo: Kutayika koyikirako ndiko kuchuluka kwa kutayika kwa chizindikiro komwe kumachitika ngati chizindikiro chikudutsa chophatikizira. Imawonetsedwa mu decibels (dB) ngati mtengo woyipa. Kutayika kwapang'onopang'ono kumasonyeza mphamvu yodutsa chizindikiro, ndipo ndikofunikira kuchepetsa kuti mupewe kuwonongeka kwa chizindikiro.

7. VSWR: Voltage Standing Wave Ratio (VSWR) ndi muyeso wa momwe cholumikizira chimasamutsa mphamvu kuchokera pa siginecha yolowera kupita ku siginecha yotulutsa. Mtengo wotsika wa VSWR ukuwonetsa kuyendetsa bwino kwa mphamvu.

8. Kudzipatula: Kudzipatula ndiko kuchuluka kwa kulekanitsa pakati pa zizindikiro ziwiri. Imawonetsedwa mu ma decibel (dB) ndipo imawonetsa kuchuluka komwe ma siginecha olowera ndi otuluka angapatulidwe kuti asasokonezedwe.

9. Mitundu Yolumikizira: Mitundu yolumikizira imatanthawuza mtundu ndi kukula kwa cholumikizira chomwe chimagwiritsidwa ntchito polumikizira ndi kutulutsa kwa cholumikizira. Mitundu yolumikizira wamba yophatikizira ma transmitter amphamvu kwambiri imaphatikizapo 7/16 DIN, 1-5/8", 3-1/8", ndi 4-1/2".
