subject: Brief Idea Of Co-axial Cable Adapters [print this page] Co-Axial Adapters are small metal adapters that connect several co-axial cables together or an end point to connect source to a receiver. The standard types of co-axial adapters are
7/16 DIN connector is power 50 ohms connector that was originally developed under Spinner,
BayonetNeill-Concelman
Omni Spectra push-on
Concelman
F- connector, used for domestic television installations and domestic satellite LNBs (75 ) worldwide.
There are many more widely used varieties.
SMA attenuators are generally used to modify signal levels from source to destination in industrial amps. They are also used in micro-waves these days.
Why use multiple adapters?
The reason behind this is, different types of equipments require different types of frequency range, specific impedance, operating current and the like factors decide which equipment
Even though more advanced technology has been developed still co-axial adapters remain an important part in all those household appliances and other entertainment systems. With developed standard for these adapters they are becoming an important part of the all entertainment gadgets and also in some other frequently used equipment.
Now you may say we can use CAT-5 cable as they cheaper but the advantage of the co-axial cable is that they minimize interference and also handle the equipments better than the former. So these cables are more widely used. Even 46GHz, the 2.4mm, 1.85mm and the 1mm connector exist. We have similarities to the SMA connector but which are geometries incompatibly scaled. These have mode-free operation to 50, 65, and 110GHz respectively
These are typically rated for mode free operations from a DC supply to 18 GHz though some other versions are rated to 26.5 GHz. There are several types of adapters available as we have said and their rated power and other things differ according to the manufactures and equipments they are meant to serve.
Reverse Polarity SMA attenuators are that type of SMA which reverses the gender of the interface.
Frequency
With the rise in the frequency level, extreme precision is required in the resistance. Normally in the market, bands can be found for frequencies of 0 6 GHz, 0 18 GHz, 0 26 GHz, 0 40 GHz, 0 50 GHz as well as 0 65 GHz.
Directionality
SMA attenuators with small signal are two way. The majority of attenuators with high power is one way and requires associated degrees of input and amp as well as output and amp. It might prove to be risky with the DUT swinging backwards. This might also be an outcome of the electrical devices working at extreme powers used without the attenuator chips.
QMA Connectors and Times LMR 400
QMA are generally quick disconnecting versions of SMA kind and they share an identical build that allows connation to offer efficient performance. The edges of the electrical performance of the QMA deal with RF performance of low loss up to 6 GC.
In layman's terms, a Times LMR 400 comes across as a wire-free bridge equipped to offer several complete networks for users to communicate transparently over long distances.
