The COVID-19 virus outbreak is causing massive disruption to the world’s health, and the ainfo Waveguide Connectors market will hit hard in 2020. The virus has been spreading to almost every country worldwide, and the World Health Organization has declared it a public health emergency. The impact is already being felt globally, and it will continue until the disease is completely eradicated. The virus has led to travel bans, flight cancellations, restaurant closures, and a massive slowdown in the supply chain. It has also resulted in a growing panic among the population and uncertainty regarding the future.
Ainfo Waveguide: Covid-19 pandemic
The World Health Organization recently published a myth-buster infographic to combat conspiracy theories regarding the COVID-19 pandemic. This new pandemic and the introduction of 5G mobile technology have coincided, and many conspiracy theories have linked the two. In addition, various countries have had dozens of arson attacks on telecom masts. In the United Kingdom, 61 suspected arson attacks, and over twenty in The Netherlands were reported.
Application of waveguides in microwave communications
Waveguides are metal pipes that facilitate the transfer of radio waves. The outer walls of the waveguide are usually fitted with microwave windows to ensure that radiation reaches the desired destination. While short cross-sections of transmission lines can sustain a microwave signal at high frequencies, these low-performance lines have low voltage ratings and considerable power loss. Waveguides, on the other hand, can maintain a higher power density and are helpful in many different microwave applications.
Waveguides are commonly used in microwave ovens, radar installations, and space crafts. They are also widely used as passive components in microwave communications. However, waveguides are challenging to install, requiring special couplings.
Impedance matching of waveguides to antennas
Impedance matching of waveguides to radio antennas can be accomplished using several techniques. One method involves using a conductive post with parts in both the electric and magnetic planes. This conductive post will provide an equivalent parallel-LC circuit across the waveguide, acting as a high shunt resistance below resonance and an inductive or capacitive reactance above resonance.
The dipole element, which comprises a metallic strip with the required electrical dimensions, is printed on a dielectric material and then displaced from the resonator according to its prescribed performance. The dipole element must choose not to disturb the antenna’s Tx irises or the other antenna element’s distinguishing characteristics.
Typical VSWR of flexible/twist waveguides
One crucial parameter to consider when choosing a flexible/twist waveguide is its length. Most companies offer flexible waveguides with fixed sizes, but many others provide flexible waveguides with custom lengths. Everything RF offers a wide selection of flexible waveguides from leading manufacturers. Users can browse product specifications, download datasheets, and request a quote to find the right solution for their application.
One advantage of flexible/twist waveguides is their high-frequency sensitivity. It is because they have low VSWR. Adjustable/twist waveguides can deliver up to 5 kW of peak power and have low insertion losses. Another key advantage is their pressurized capabilities.
Manufacturers of flexible/twist waveguides
Unlike traditional waveguides, flexible/twist waveguides can bend and twist, reducing insertion loss while still providing excellent performance. The waveguides can be bent along the H or E plane and turned to match the load phase.
Flexible waveguides can be used in various microwave and millimeter-wave applications. Their operating frequencies are typically within a 1.2 GHz-to-40-GHz range. Depending on the desired wavelength, they are available in six to 60-inch lengths. They deliver a VSWR of 1.07:1 and have insertion losses as low as 0.06 dB. In addition, they are compatible with pressurized applications.
Flexiguide is the world’s largest manufacturer of flexible/twist waveguide products. The company also manufactures associated products. Flexiguides start as a thin strip of silver-plated brass precision-rolled into a three-dimensional profile. This core is then helically wound around a rotating mandrel. This process ensures a uniform cross-section, and internal silver plating prevents loss. The center is not pressure-tight without a jacket.
