Vswr, dawo da asara (rl), nuna wuta, kuma iko da aka watsa

Dangantaka tsakanin wutar lantarki mai tsayi (VSWR), dawo da asara (rl), nuna iko, kuma iko mai watsa da aka haɗa ta hanyar daidaitawa (γ). Da ke ƙasa akwai mahimman tsari da matakai don juyawa:

### ** Core Tsarin Tsarin **
1. ** yanayi mai kyau (γ) **:

\ Gamma = \ FRArc {rubutu {vswr} - 1} {rubutu {vswr} + 1} +

2. ** vswr ** daga γ:

\ rubutu {vswr} = \ FRArc {1 + | \ gamma |} {1 - | \ gamma |}

3. ** Komawa Asarar (RL) ** A DB:

\ rubutu {rl (DB)} = -20 \ log_ {10} (| \ gamma |)

4. ** nuna iko (%) **:

P _ {{{{{{{ROML} {= | \ gamma | ^ 2 \ sau 100 \%

5. ** Powerarfin da aka watsa (%) **:

P _ {rubutu {ARES} = \ hagu (1 - | \ gamma | ^ 2 \ dama) \ sau 100 \

### ** Matakan Canza **
#### ** 1. Fara da VSWR **:
- lissafta γ:

\ Gamma = \ FRArc {rubutu {vswr} - 1} {rubutu {vswr} + 1} +

- Yi amfani da γ don nemo RL, yana nuna iko, da kuma ikon da aka watsa ta amfani da dabarun da ke sama.

#### **. Fara da dawo da asarar (RL a DB) **:
- lissafta γ:

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

- Yi amfani da γ don nemo VSWR, ya nuna iko, kuma iko mai watsa.

#### ** 3. Farawa tare da Warfed / Wayar da aka watsa ta **:
- Don ** Work Power ** (\ (shafi) rubutu {sake toctal} {{^)

| Gamma | = \ sqrt {FRRT _ pt \ rubutu {sake to} {{} {100} {}

- don ** Weldited Power ** (\ (shafi) rubutu {trasp din} \ trans \ ^ ire)

| Gamma | = \ sqrt {1 - \ frac {p _ {\ rubutu {truya}} {truya}} {Action}} {100}

- Yi amfani da γ don lissafin VSWR da RL.

### ** Table Table **
| ** vswr ** | ** dawo da asara (DB) ** | ** Warfafa Power (%) ** | ** Powerarfin Shafin (%) ** |
|----------|----------------------|-------------------------|---------------------------|
| 1.0 | ∞ (cikakken wasa) | 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% |

### ** Key Notes **
- A ** vswr na 1: 1 ** yana nufin babu tunani (γ = 0, rl = ∞).
- ** Babbar VSWR ** ko ** ƙananan rl ** yana nuna ƙarin tunani sosai.
- ** Wutar da aka watsa ** an inganta lokacin da vswr ≈ 1.
