QMA coaxial connectors are generally introduced together with QN connectors. Both QMA and QN connectors are quick-plug connectors, which have two main advantages: one is that they can be connected quickly, and the time to connect a pair of QMA connectors is much lower than the time to connect SMA connectors; the other is quick-plug connectors. Suitable for connecting in small spaces. The size of the QMA connector is comparable to the SMA connector, and the recommended frequency of use is 6GHz. The size of the QN connector is comparable to the N-type connector, and the recommended frequency of use is 6GHz.
In terms of connection method, QMA often uses Quick-Lock Coupling, which has excellent mechanical connection and requires a lot of force to pull it out. At the same time, the speed of screwing is faster than that of the threaded type. As a quick-plug coaxial connector, it is small in size and light in weight, and is widely used in mobile communication base stations, networks and test equipment.
Low Loss QMA Right Angle Male to SMA Male Cable Assemblies
A PE(F) dielectric with a VoP parameter of 84% was used, which has the advantage of low insertion loss compared to solid-state dielectrics. This flexible RF cable assembly is ideal for applications requiring flexing environments. The maximum operating frequency is 5.8 GHz. The double shielding layer of this N-head cable assembly is covered by a tinned copper layer on the aluminum tape, and the shielding effect is greater than 90dB.
