VSWR, Laghachi (RL), ike gosipụtara, na ebugharị

Mmekọrịta dị n'etiti Volge Stage Stage (VSWR), Laghachi (RL), ike gosipụtara, ma na-egbochi ike site na ọnụ ọgụgụ na-eche nche (γ). N'okpuru ebe a bụ usoro igodo na usoro maka ntụgharị:

### ** Core forlas **
1.

\ Gamma = \ Frac {\ Text {vsrr} - 1} Text {vsw} + 1}

2. ** vwr ** site na γ:

Text Text {VSWR} = \ Frac {1 + | \ Gamma | {1 - | \ Gamma |}

3.

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

4. ** Egosiputara ike (%) **:

P _ \ Text {Ntughari} = | \ Gamma | ^ 2 \ Time 100 \%

5. ** Travemist ike (%) **:

P _ \ Text {trans =}} (1 - | \ Gamma | ^ 2 \ Aka) \ Oge

### *** Nzọụkwụ ntụgharị **
#### ** 1. Bido na VSWR **:
- Gbakọọ γ:

\ Gamma = \ Frac {\ Text {vsrr} - 1} Text {vsw} + 1}

- Jiri γ ka ịchọta Rl, ike gosipụtara, na ebugharị site na iji usoro dị n'elu.

#### ** 2. Bido na Lot Love (RL na DB) **:
- Gbakọọ γ:

| Gamma | = 10 ^ {\ Text {RL} / 20}

- Jiri γ ka ịchọta VSTR, ike na-egosipụta ike, na mbufe.

#### ** 3. Na-amalite site na ike / ebugharị **:
- Maka ** gosipụtara ike ** (\ (p _ \ Text {resk})

| Gamma | = \ SQRT {\ Frac {p _ \ Text {res}} {100}}

- maka ** Tratrik ** (\ (p _ \ Text {trans}))

| Gamma | = \ SQRT {1 - \ Frac {p _ _ set {trans}}}}}}

- Jiri γ iji gbakọọ VSWR na Rl.

| ** vwr ** | ** Laghachifu (DB) ** | ** Egosiputara ike (%) ** | ** Mbugharị ike (%) ** |
|----------|----------------------|-------------------------|---------------------------|
| 1.0 | (Egwuregwu zuru oke) | 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% |

### ** ndetu **
- A ** VSWR nke 1: 1 ** pụtara enweghị ntụgharị (γ = 0, rl = ∞).
- ** elu VSWR ** ma ọ bụ ** Obere RL ** na-egosi ike gosipụtara.
- ** bufee ike ** na-emegharị mgbe VSWR ≈ 1.

Jiri usoro ndị a tụgharịa n'etiti parameters maka enweghị njikọ kwekọrọ na sistemụ RF.
