Semi rigid coaxial cables are essential in high frequency – applications up to 110 GHz. What sets them apart is their unique mechanical behavior: they can be bent into their final shape—by hand or machine—and retain that shape permanently. This makes them ideal for RF environments requiring precise routing and...

Coaxial cables are widely used across many industries, from precision RF measurements to high-speed data transmission. In some cases, the key requirement is preserving the exact waveform of a signal. In others, the goal is minimizing attenuation across the transmission path. For optimal performance, the goal is always the...

To transmit signals from point A to point B, one could use two parallel wires. This approach even works in the RF range if impedance is carefully controlled. However, the downside is that the electromagnetic field radiates outward, making it vulnerable to nearby disturbances and environmental interference. Waveguides, on...

Modern test laboratories are equipped with the most sensitive instruments available today. Staff members have undergone extensive training and preparation for increasingly complex measurement requirements. For each of the engineers involved, precision and utmost accuracy are a given. With a significant budget already invested, there’s no room for compromise—the...

Selecting the optimal RF measurement cable is not a matter of luck but of informed decision-making. Each cable must meet a specific combination of performance, durability, and environmental tolerance. Measurement engineer Stefan Burger, founder of Delta Gamma RF-Expert in Australia, shared critical insights on how to ask the right...
