Compared with radio frequency signals, the measurement of millimeter wave connectors needs to be more meticulous and cautious. The signal analyzer can now extend the frequency coverage to 110GHz and above in a coaxial manner. Low-noise, high-precision, and wide-bandwidth test solutions allow engineers to focus on their design and measurement results without having to be distracted by building test systems that require complex calibration.

The most important millimeter wave connection in the test system is undoubtedly the connection on the front panel of the test equipment. The pin (male) connector is the first choice over other connections in the millimeter wave frequency band. Usually in daily use, a female-female "connector protector" can be connected to the male connector of the instrument to reduce the probability of damage to the instrument itself.
As the frequency increases, the impedance problem and the loss of the cable, connector, or adapter will get worse. Therefore, it is also very important to keep the cable as short as possible and to keep the DUT and the test instrument as close to each other as possible.
1. Connector maintenance
From the appearance, these connectors do not seem to be damaged or displaced, but there is some pollution. Due to their small size, millimeter wave connectors require special materials and technologies to keep them clean. The connector gauge can ensure that the mechanical dimensions of the millimeter wave connector are within a strict tolerance range, thereby ensuring impedance matching.
2. Appropriate connector torque
Constant torque and proper use of torque wrenches can minimize impedance mismatch and loss between millimeter wave connections. Mastering the essentials of operation is essential to avoid damaging these connectors. Otherwise, it is very likely to damage expensive connectors.
3. External mixing
Considering the millimeter wave connection loss of the coaxial cable and the cumbersome physical connection effect caused by the waveguide, it may be necessary to consider the use of an external mixer. The external mixer allows users to build a remote test bench and place the measurement end face on the port of the DUT.
The 1.85mm connector is a high-density millimeter wave connector. And someone also calls it a V connector. The interface port of the 1.85mm RF connector is compatible with the 2.4mm connector. This type of connector is air and high-strength polyimide (PEI as a supporting medium, which can provide the lowest reflection coefficient after optimization with advanced finite element electromagnetic simulation technology, and the frequency of use is DC~67GHz.
Because of the many advantages of the millimeter wave connector, it is very popular in the international market. Millimeter wave connectors are indispensable in the construction of communication infrastructure in many countries.
