VSWR, hoki mai te ngaronga (RL), te whakamarama i te mana, me te mana whakawhiti

Ko te whanaungatanga i waenga i te ngaohiko e tu ana te riri ngaru (VSWR), te toenga (RL), te mana whakaata, me te kaha whakawhiti, me te hono atu ki te taha o te whakaaro huritao (γ). Kei raro nei nga tikanga matua me nga waahanga mo te hurihanga:

### ** nga tātai matua **
1. ** Whakaataata Whakaahuahia (γ) **:

\ Gamma = \ Frac {\ kuputuhi {\wr} - 1} {\ \ \ \ vswr} + 1}

2. ** vswr ** Mai i te γ:

\ kuputuhi {vswr} = \ Frac {1 + | \ gamma |} {1 - | \ gamma |}

3. ** Te toenga (RL) ** I DB:

\ kuputuhi {rl (db)} = -20 \ log_ {10} (| xamma |

4. ** Te mana whakaata (%) **:

P _ {\ kuputuhi {refl} = | \ gamma | ^ 2 \ wa 100 \%

5. ** Mana Whakakore (%) **:

P _ {\ \ kuputuhi {trans}} =

### ** Nga Mahi Whakawhiti **
#### ** 1. Ka tiimata me te vswr **:
- Tātai γ:

\ Gamma = \ Frac {\ kuputuhi {\wr} - 1} {\ \ \ \ vswr} + 1}

- Whakamahia kia kitea te RL, te mana whakaata, me te mana whakawhiti ma te whakamahi i nga tātai i runga ake nei.

#### ** 2. Ka tiimata me te ngaro o te hokinga (RL i DB) **:
- Tātai γ:

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

- Whakamahia γ kia kitea te VSWR, he mana whakaata, me te mana whakawhiti.

#### ** 3. Ka tiimata me te Whakanuia / Whakanui Mana **:
- Mo te ** e whakaata ana i te mana ** (\ (p _ \ \ refl} \ \)):

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

- Mo te ** Te Mana Whakakore ** (\ (p _ {\ {\ {Tran} \ \)):

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

- Whakamahia γ hei whakariterite i te vswr me te rl.

### ** Tauira Tohu **
| ** vswr ** | ** Te toenga (DB) ** | ** Te mana e whakaata ana (%) ** | ** Mana Whakakore (%) ** |
| --- -
| 1.0 | ∞ (tukinga tino tika) | 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% |

### ** tuhinga matua **
- A ** vswth o te 1: 1 ** te tikanga o te whakaata (γ = 0, rl = ∞).
- ** teitei ake vswr ** ranei ** RL ** e whakaatu ana i te mana whakaata.
- ** Ko te mana whakawhiti ** ka whakarahihia i te wa o Vswr ≈ 1.
