Vswr, Gusubira igihombo (RL), Imbaraga zagaragaye, nimbaraga zaboherejwe

Umubano uri hagati ya voltage uhagaze neza (VSWR), gutakaza igihombo (RL), kandi imbaraga zandujwe, kandi imbaraga zandujwe zirahujwe binyuze muburyo bwo kwerekana (γ). Hano hepfo formula nintambwe zo guhinduka:

### ** fore formulaire **
1. ** Gukora hamwe (γ) **:

\ Gamma = \ frac {\ inyandiko {Vswr} - 1} {\ inyandiko {Vswr} + 1} 1}

2. ** vswr ** kuva γ:

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

3. ** Gusubirayo (RL) ** muri DB:

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

4. ** Imbaraga zagaragaye (%) **:

P _ {\ inyandiko {reff}} = | \ gamma | ^ 2 \ Ibihe 100 \%

5. ** Imbaraga (%) **:

P _ {\ inyandiko {Trans}}}}} \ ibumoso (1 - | gamma | ^ 2 \%

### ** Ihinduka ryintambwe **
#### ** 1. Guhera kuri VSWR **:
- Kubara γ:

\ Gamma = \ frac {\ inyandiko {Vswr} - 1} {\ inyandiko {Vswr} + 1} 1}

- Koresha γ kugirango ubone RL, imbaraga zagaragaye, nimbaraga zandujwe ukoresheje formula hejuru.

#### ** 2. Guhera hamwe no gutaha (RL muri DB) **:
- Kubara γ:

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

- Koresha γ gushakisha vswr, zagaragaje imbaraga, kandi zoherejwe.

#### ** 3. Guhera hamwe / gutangwa imbaraga **:
- Kuri ** Imbaraga zamashanyarazi ** (\ (p _ {\ inyandiko {reff}}}}}} \)))))))))))))))))))):

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

- Kuri ** Amashanyarazi ** (\ (p _ {\ inyandiko {tran Trans}}} \)))))))):

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

- Koresha γ kugirango uhuze Vswr na RL.

### ** URUGERO **
| ** vswr *** | ** Gusubirayo (DB) ** | ** Imbaraga zagaragaye (%) ** | ** Amashanyarazi (%) ** |
| ---------- | ---------------------- | ----------------------------------------- |
| 1.0 | (Guhuza neza) | 0% | 100% |
| 1.5 | 14.0 DB | 4% | 96% |
| 2.0 | 9.5 db | 11.1% | 88.9% |
| 3.0 | 6.0 DB | 25% | 75% |

### ** Inoti ZIKURIKIRA **
- ** vswr ya 1: 1 ** bisobanura nta myigaragambyo (γ = 0, rl = ∞).
- ** Vswr Hejuru ** cyangwa ** yo hepfo rl ** yerekana imbaraga zigaragara.
- ** Amashanyarazi ** Amahirwe Iyo VSWR ≈ 1.
