High-frequency Coaxial Connectors Test in ZOMWAVE

An important feature of coaxial technology requires that their power and voltage-related media breakdown are much lower than that of similar frequencies. If the weight and cost is highly concerned, this may be acceptable. However, problems in high temperature BNC connector and high-pressure material degeneration and material performance may reduce the feasibility of coaxial technology in aerospace applications.

Adapter and terminal

Since each adapter and terminal Coaxial Connectors introduce unnecessary insertion loss and reflection, carefully select the correct component to prevent unnecessary signal degradation and may have multiple forms of sensitive electronic device adapters and terminals, usually coaxial or waveguides. For high power applications. In addition, the BNC connector adapter may be more complex because the size and type of the adapter may be different. In addition, the adapter itself may introduce turning or bending.

The power and frequency range of the adapter must be carefully examined, especially if the adapter is a waveguide to coaxial conversion. The waveguide naturally only transmits bandwidth of the band range with high signal fidelity, where the coaxial technique has only a cutoff frequency. However, different coaxial connector types also have different power and frequency capacity. If the adapter is a transition between two different coaxial connector types, the frequency, power processing, PIM, insertion loss, and other parameters will be affected.

The terminal preliminates their Coaxial Connectors potential extreme RF energy within the device. Typically, terminals for high power applications will have a heat dissipation metal body and may force air heat management. The impedance matching of the terminal is absolutely essentially critical because the unpredictable reflection may lead to over-power and overvoltage conditions in the upstream electronic device. This BNC connector may be dangerous while delivering the high power amplifier (HPA) to a terminal that does not meet enough VSWR specification, as it may permanently damage the HPA.

Attenuator

Like a terminal, the attenuator Coaxial Connectors is designed to dissipate RF energy within the device main body without any unwanted signal distortion or reflection. There is a fixed and variable attenuator. For most extremely high power applications, fixed attenuators are more common. Like the terminator, they can be a waveguide or coaxial. In addition, the attenuator can also be an adapter of different sizes of coaxial connector sizes, although this very little use of waveguide connector.

The waveguide directional coupler may have coaxial output because the power level of the coupling signal is low enough, and can be transmitted in a lower weight and cost coaxial transmission line.

The metal radiator usually surrounds the body, even forced cooling according to the amount of power dissipated by the attenuator. The higher the frequency, power processing, and attenuation, and RF energy is converted to heat. When installing the attenuator, make sure BNC connector the attenuator gets sufficient ventilation and is not important to be close to the position close to other heat dissipation electronic devices.

Filter

Since the filter can be used as Coaxial Connectors a reflector of the frequency band selective attenuator or the extracted signal, it is necessary to take into account the type of upstream electronic device and the signal of the input filter. The absorption filter absorbs the RF energy from the extracted signal and converts it to heat. Among them, the reflective filter redirects the RF energy backward. This type of filter may damage sensitive upstream electronic devices due to overtefficient or overvoltages. According to the filter technology and structure, the power processing capacity of the filter is generally highly dependent on the frequency.

As with most RF and microwave components, the power threshold of higher frequency components is lower than BNC connector its low power component. The relative dimensions and materials of the filter will have a significant impact on power and frequency limits. The passband of the filter naturally decays the signal, so that the passband characteristics are equally important to the in-band filter characteristics in terms of RF energy absorption or reflection.
