RF coupling

[/ɑːr ɛf ˈkʌplɪŋ/]
nounpl: RF couplings
acoplamento de radiofrequência
1. The transfer of electromagnetic energy between two circuits or transmission lines through radiofrequency signals, typically achieved through capacitive, inductive, or direct connections
The RF coupling between the transmitter and antenna must be optimized to minimize signal loss.
O acoplamento de radiofrequência entre o transmissor e a antena deve ser otimizado para minimizar a perda de sinal.
2. A device or technique used to connect radiofrequency circuits while maintaining signal integrity and impedance matching
We installed an RF coupling capacitor to connect the two amplifier stages.
Instalamos um capacitor de acoplamento de radiofrequência para conectar os dois estágios do amplificador.
3. The mutual influence or interaction between radiofrequency signals in adjacent circuits or components
Excessive RF coupling can cause unwanted feedback in sensitive receiver circuits.
O acoplamento excessivo de radiofrequência pode causar realimentação indesejada em circuitos receptores sensíveis.
RF coupling is a fundamental concept in electrical engineering, telecommunications, and broadcast industries. In Brazil, as in the USA, it is primarily used in technical and professional contexts within the fields of electronics, telecommunications, and radio engineering. The term maintains the same technical meaning across both English-speaking and Portuguese-speaking regions, though it may be abbreviated differently in informal technical communications.
