I-VSWR, ilahleko (RL), eboniswe amandla, kwaye usasaze amandla

Ulwalamano phakathi kwe-voltage ratio (vswr), ukubuyisa ilahleko (i-RL), eboniswe amandla, kwaye idluliselwe amandla, i-γ). Apha ngezantsi kukho iifomula eziphambili kunye namanyathelo okuguqula:

### ** Ifomula engundoqo **
1.

\ Gamma = \ frac {\ itekisi {vswr} - 1} {\ itekisi {VSWR} + 1}

I-2. ** vswr ** ukusuka γ:

\ Itekisi {vswr} = \ frac {1 + | \ gamma |} {1 - | \ gamma |}

I-3. ** Ilahleko (RL) ** kwi-DB:

\ isicatshulwa {rl (i-DB)} = -20 \ Log_ {10} (| \ gamma |)

I-4.

P _ {\ itekisi {hil}}}}}}}} \ gamma | ^ 2 \ Times 100 \%

I-5. ** Amandla adluliselweyo (%) **:

P _ {\ {\ {trans}}}}}}}}}}}

###
#### *** 1. Ukuqala nge-vswr **:
- Bala γ:

\ Gamma = \ frac {\ itekisi {vswr} - 1} {\ itekisi {VSWR} + 1}

-Sebenzisa γ ukufumana i-RL, ibonakalise amandla, kwaye idluliselwe amandla asebenzisa iifomula ezingentla.

#### *** 2. Ukuqala ngelahleko ye-RL (RL kwi-DB) **:
- Bala γ:

| \ Gamma | = 10 ^ {- \ isicatshulwa {RL} / 20}

-Sebenzisa γ ukufumana amandla eVSWR, oboniswe amandla, kunye namandla adluliselwa.

#### ** 3. Ukuqala ngokubonakalayo / ukuhambisa amandla **:
-Umsebenzi obonisiweyo ** (\ (p _ {\ itekisi {ral}} \):

| \ Gamma | = \ sqrt {\ frac {\ _ {\ itekisi {ye-Garl}} {100}}}

-Umsebenzi ** odluliselweyo ** (\ (p _ {\ itekisi {trans}} \):

| \ Gamma | = \ sqrt {1 - \ frac {p _ {\ {trans}}}}}}}}

-Sebenzisa γ ukufaka i-vswr kunye ne-RL.

### ** Umzekelo weTafile **
| ** vswr ** | ** Ukubuya ilahleko (i-DB) ** | ** IXESHA LOKUGQIBELA (%) ** | ** I-STORTATIONTR (%) ** |
| ----------------------------------------------------------
| 1.0 | ∞ (Umdlalo ogqibeleleyo) | I-0% | I-100% |
| 1.5 | 14.0 I-DB | I-4% | I-96% |
| 2.0 | 9.5 I-DB | I-11.1% | I-88.9% |
| 3.0 | 6.0 I-DB | I-25% | 75% |

### ** amanqaku aphambili **
-I-A ** vswr ye-1: 1 ** kuthetha ukuba akukho mfuneko (γ = 0, RL = ∞).
- ** I-vswr ephezulu ** okanye ** i-rl ye-RL ** ibonisa amandla abonakalisiweyo.
- ** I-START AMANQAKU ** IYAQHUTYWA XA KUPHELA I-VSWR ≈ 1.
