The Selection of RF Attenuator
Ⅰ. About the RF attenuatorThe RF attenuator can reduce the power of the RF signal. Typically, radio frequency signals are transmitted through a coaxial cable, and the attenuator is used online with t...
Different Types of RF Attenuator
Ⅰ. Why do you need an RF attenuator?In RF circuits, a higher signal level is usually better. Because improving the signal level can improve the signal-to-noise ratio (SNR) and reduce problems caused ...
What is a Helical Antenna?
1. What is a helical antenna?A helical antenna is an antenna with a spiral shape. It is composed of a metal spiral wire with good electrical conductivity. It is usually fed by a coaxial wire. The core...
Two Working Modes of Helical Antenna
Many antennas deployed in basic communication systems are linearly polarized, which means that the polarization is limited to a single plane in terms of the direction of the electric field. Antennas t...
