Rotary joints, unlike typical adapters, have the ability to rotate about the axis perpendicular to the wave propagation direction. While maintaining transmission properties, these joints can rotate freely 360 degrees. This type of joint is necessary for any application that has a rotating section, such as a rotary antenna (air surveillance), missile guidance system, and ..

Controlling the phase of RF/microwave signals is an essential aspect of most modern communications, radar, and testing applications. Phase adjustments can be used to create a variety of effects, including combining, subtracting, and aligning signals, as well as part of phased-array antenna technology. Moreover, phase variations in a radar response can be used to distinguish important ..

RF/microwave power sensors/meters, or wattmeters, are one of the simplest and most commonly used test instruments for diagnostics and repair of radio systems. These devices essentially extract a portion of the energy from an RF device or antenna, and using calibrated and traceable standards, present a power reading. RF Power sensors/meters are often used in ..
