About the advantages and disadvantages of wireless transmission
Regarding wireless home theater, Xiao Bian mentioned in the article "Some predictions for the development of home theater" that wireless home theater is a development trend of home theater in the future. Today, everyone will come along with Xiaobian to learn about the advantages and disadvantages of wireless transmission.
Let me talk about the advantages of wireless transmission! The first advantage of wireless transmission is that it can be protected from the connection line and is convenient to use. It is a convenient thing to think about it in the range that wireless signals can cover. There is also an advantage in wireless transmission, which may not be felt by ordinary friends. Wireless transmission can allow more young people to access audio and video products and music.
Through wireless transmission, we can connect mobile phones, computers, walkmans and audio equipment, so that more friends can contact or use audio and video products, from which we can also train some music enthusiasts.
After talking about the advantages, let's take a look at the shortcomings of wireless transmission. Using wireless, every problem that comes to mind is the interference problem. If this problem occurs, we can only avoid the signal at the same frequency. Another downside is that the quality of music is compromised by wireless transmission, which is why many enthusiasts insist on wired transmission.
Coaxial Power D-Sub Solder Cup Contacts with Mixed or Full Layout
Transmit Radio Frequency Signals
The Coaxial D-Sub have like the Power D-Subr replaced the two rows in a Standard Density connector with a coaxial contact that take up about the same size as the two rows of signal contacts. The Coaxial D-Sub is exactly the same size as the Standard Density connector but instead of example 9 positions of signal pins it has 2 power contacts , or instead of 37 positions of signals it has 8 coaxial contacts.
The Impedance for the coaxial contacts are 50Ω or 75Ω
The Coaxial D-Sub with Mixed Layout mixes both coaxial contacts and signal contacts in the same connector. For example the same size as a 15 position Standard Density D-Sub you can have what we call a 7W2, which means there is 7 contacts where 2 of them are coaxial contacts, which means there are 5 signal contacts, so 5 signals and 2 coaxial. See the Layout in the Tech Specs on the bottom, there are a lot of combinations of the Mixed Layout alternative.
Antenk's Coaxial D-Sub connectors are available in 5 standard shell sizes with 23 multiple contact arrangements. These reliable, robust combination d-sub connectors allow a combination of signal and coaxial contacts in cable mount, vertical board mount & right angle board mount termination type variations.
