Information

In the realm of wireless communication, delving into the intricacies of RF operational characteristics is crucial. RF signals, as they propagate through a medium, adopt various propagation modes, encompassing absorption, reflection, scattering, refraction, diffraction, loss, gain, and multipath.

1.1 Absorption

Absorption refers to the phenomenon where RF signals, in the course of propagation, encounter materials that absorb their energy, leading to signal attenuation. Materials with higher density, such as brick walls and concrete, result in more severe signal attenuation. Additionally, considerations for human body absorption and user density are essential in the design phase.

1.2 Reflection

Reflection involves RF signals encountering a medium interface, changing their propagation direction, and returning to the original medium. In wireless local area networks, careful attention to RF signal reflection is crucial, as it can lead to multipath phenomena, impacting signal strength, quality, and even causing data loss.

1.3 Scattering

Scattering occurs when RF signals, during propagation, encounter rough or uneven objects, deviating from their original direction and dispersing.

1.4 Refraction

Refraction is the phenomenon where RF signals change their propagation direction when entering another medium at an oblique angle. Factors such as water vapor, air temperature, and air pressure significantly influence refraction.

1.5 Diffraction

Diffraction refers to RF signals bending and spreading when encountering obstacles. Diffraction may result in signal distortion.

1.6 Attenuation

Attenuation, also known as loss, signifies the reduction in signal amplitude or strength during RF signal propagation in cables or air. Diffraction may lead to signal distortion.

1.7 Gain

In contrast to loss, gain represents the increase in RF signal amplitude or signal enhancement.

1.8 Multipath

Multipath entails two or more signals arriving at the receiver simultaneously or with very short time gaps. The same signals traversing different paths combine at the receiver, amplifying or diminishing the signal.

In the realm of RF technology, our company, AmpliVisionS, specializes in developing high-performance RF power amplifiers that seamlessly align with the intricate characteristics discussed above.
