Model NO.: ST-AC004

Antenna couplers and RF couplers are crucial in RF systems. Antenna couplers optimize impedance matching between the transmission line and the antenna, enhancing power transfer and signal quality. RF couplers, meanwhile, split RF signals, enabling signal monitoring, measurement, and analysis without disrupting the main signal path. Both are essential for ensuring efficient operation, diagnosing issues, and maintaining the performance of RF - based communication systems.

Application

The RF Coupler`s fundamental principle and function :

Antenna coupler is born with the development of radio terminals in recent years, because the signal is too strong for ordinary antenna , The antenna coupler will have a reflective resonance, affect the test accuracy. RF coupler can be smooth in receiving and transmitting signals, can achieve product batch testing and product development needs. Capacitors and inductors on the circuit board converts the energy of electromagnetic waves, and spread in a fixed direction instead of external electromagnetic fields can also be converted to electrical energy.  As the best means of receiving signals on the external antenna , and energy.
