The RF connector is usually considered as a component attached to the cable or installed on the instrument as a component for electrical connection or separation of the transmission line. With the advancement of 5G commercial use, 5G equipment is facing upgrading, and the traditional RF connector is The transmission rate and reliability can no longer meet the needs of 5G large-scale antennas.

The focus of antenna design lies in the high-speed signal transmission between a large number of antenna arrays and RF transceivers between PCB boards. Therefore, the development of high-speed, high-power, and small-size RF connectors is imminent. Simply put, we need " smaller and lighter " high-end connectors.

For example, RRH (remote radio head) , which is widely used in distributed base station systems, must be designed to be very compact in order to be easily, conveniently and reliably installed on the top of towers and in dense urban environments. Controlling its size requires that the coaxial interconnection system that carries its radio frequency signal transmission must be more compact and compact. Traditional and complicated cable assembly connections are being replaced by simple, compact and reliable " board-to-board " coaxial connector connections that can carry more than 100W of radio frequency signal power .

Features:

◆ Small size, quick plug-in and self-locking system, easy to install

◆ There are different types of plugs such as straight type and 90 degree angle type.

◆ High frequency, transmission frequency is 3MHz-30MHz

◆ Multiple functions, in addition to the role of a bridge, it also has the functions of processing signals, such as filtering, phase modulation, mixing, attenuation, detection, amplitude limiting, etc.

◆ Low standing wave, low loss: to meet the needs of weapon systems and precision measurement

◆ Large capacity and high power: mainly to meet the needs of rapid development of information

Application scenarios:

QM connectors have an extremely wide range of applications, which can be used in mobile phones, wireless communication equipment, electronic measuring instruments, GPS , wireless local area networks, Bluetooth devices and any application that requires the use of small coaxial connectors for high-frequency transmission.
