I-VSWR, ukulahleka kwembuyiselo (RL), Amandla abonisiwe, namandla adlulisiwe

Ubudlelwano phakathi kwe-Voltage Stave Wave Ratio (VSWR), ukulahlekelwa yi-Return (RL), amandla abonisiwe, namandla adlulisiwe axhumene ne-Coeffled (γ). Ngezansi amafomula asemqoka nezinyathelo zokuguqulwa:

### ** Amafomula Okugogo **
1.

\ Gamma = \ frac {\ umbhalo {vswr} - 1 \ \ {vswr} + 1}

2. ** VSWR ** kusuka ku-γ:

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

3. ** Return Loss (RL) ** Ku-DB:

\ Umbhalo {rl (db)} = -20 \ log_ {10} (| \ gamma |

4. ** Amandla abonisiwe (%) **:

P _ {\ \ \ {pand}} = | \ gamma | ^ 2 \ times 100 \%

5. ** Amandla adlulisiwe (%) **:

P _ {\ \ \ {trans}} = \ kwesokunxele (1 - \ \ gamma | ^ 2 \ kwesokudla) ^ 2 \

### ** Izinyathelo Zokuguqula **
### ** 1. Ukuqala nge-VSWR **:
- Bala u-γ:

\ Gamma = \ frac {\ umbhalo {vswr} - 1 \ \ {vswr} + 1}

- Sebenzisa i-γ ukuthola ama-RL, amandla abonisiwe, futhi amandla adlulisiwe usebenzisa amafomula ngaphezulu.

### ** 2. Ukuqala ngokulahleka kwembuyiselo (RL ku-DB) **:
- Bala u-γ:

| \ Gamma | = 10 ^ {- \ Umbhalo {rl} / 20}

- Sebenzisa γ ukuthola i-VSWR, amandla abonisiwe, namandla adlulisiwe.

### ** 3. Ukuqala ngamandla abonisiwe / adlulisiwe **:
- Of ** Amandla abonisiwe ** (\ (P _ {\ {\ {\ {

| \ Gamma | = \ sqrt {\ frac {p _ {\ {\ {\ {\ {\}}} {100}}

- Of ** Amandla adluliselwe ** (\ (p \ _ {\ {\ {{trans}} \ \):

| \ Gamma | = \ sqrt {1 - \ frac {p _ {{{{\ {{{{trans}}} {100}}

- Sebenzisa γ ku-γ ku-vswr ne-rl.

### ** Isibonelo Ithebula **
| ** VSWR ** | ** Return Return (DB) ** | ** Amandla abonisiwe (%) ** | | ** Amandla adlulisiwe (%) ** | |
| ------------------------------------------------------
| 1.0 | ∞ (umdlalo ophelele) | 0% | I-100% |
| 1.5 | 14.0 DB | 4% | 96% |
| 2.0 | 9.5 DB | 11.1% | 88.9% |
| 3.0 | 6.0 DB | 25% | 75% |

### ** Amanothi aphambili **
- A ** vswr of 1: 1 ** kusho akukho okukhombisa (γ = 0, rl = ∞).
- ** I-VSWR ephakeme ** noma ** I-RL RL ** Ibonisa amandla aboniswe amanye.
- ** Amandla adlulisiwe ** kuyandiswa lapho i-VSWR ≈ 1.

Sebenzisa lawa mafomula ukuze uhlukanise phakathi kwamapharamitha ukufana kokufanisa kwezinhlelo ze-RF.
