RF high speed interconnection is used in many electronic products where signal transmission quality is a critical factor in applications using high speed digital signals. An RF interconnect is the complete path that connects one device to another; RF-interconnect structures include coaxial cable assemblies, microstrip transmission lines, and waveguides with RF connectors, adapters, and attenuators. ..

What is an RF Coaxial Probe? In RF applications, transmission lines generally are coaxial cables linked to circuit boards and microstrips within circuit boards. An RF coaxial probe is a measurement device used with electronic test equipment in the measurement of radio frequency (RF) signals in an electronic circuit as found in silicon wafers, dies, ..

Many coaxial connector types are available in the RF and microwave industry designed for specific purposes and applications with smaller connectors that perform into the GHz and millimeter wave range. Compatibility with other RF microwave components is achieved with universally accepted connector standards so that interconnecting coaxial modules within a system is possible and must ..

Coaxial cable is the most commonly used transmission line for RF and microwave applications, because it provides reliable transmission with the benefits of wide bandwidth and low loss and high isolation. Major manufacturers of transmitting equipment, i.e. radio and TV, radar, GPS, emergency management systems, air and marine craft, use coaxial cables. The uses of ..

Beamforming as a Buzzword Beamforming is used for directional signal transmission and reception with the versatility to change both amplitude and phase to help regulate power needs and steer the beam in the intended direction. Bandwidth from 6 to 100 GHz, or millimeter Wave (mmWave), is likely an integral part of future mobile broadband as ..

In array antennas, beamforming, also known as spatial filtering, is a signal processing technique used to transmit or receive radio or sound waves in a directional signal. Beamforming applications are found in radar and sonar systems, wireless communications, and in acoustics and biomedicine equipment. Beamforming and beam scanning are generally accomplished by phasing the feed ..

Loss, whether due to radiation leakage or conduction resonance, is a common problem in RF microwave transmission lines, especially when high-powered frequency transmissions are involved. The solution? Waveguides. Waveguide Basics A waveguide is an electromagnetic feed line used for high frequency microwave signals in high-power transmitters and receivers and is used in radar equipment, in ..

An antenna array, or phased array, is a set of two or more antennas whose signals are combined in order to improve performance over that of a single antenna. An antenna array is used to increase overall gain, provide diversity reception, cancel out interference, maneuver the array in a particular direction, gage the direction of ..

Monopole The monopole is a resonant antenna and the length of the antenna is determined by the wavelength of the radio waves being received and transmitted. A monopole antenna is usually made of a single conductor mounted over the ground with one side of the feedline from the receiver or transmitter connected to the conductor ..

Antennas are essential components of RF and microwave devices and are used in a wide variety of applications including radio and television broadcasting, radar, cellular transmission, and satellite communications to name a few. Antennas are designed to transmit and receive radio waves determined by the design of the application intended to receive the transmissions and ..
