A tunable resonator is a device used either to generate RF frequencies or select specific frequencies from a signal. It exhibits resonance in that it naturally oscillates at frequencies known as resonant frequencies. These oscillations can be either electromagnetic or mechanical. Tunable resonators are used in a wide range of radio devices, specifically tunable radios, ..

In most RF systems, the production, transmission, and reception of a radio frequency signal is accomplished by way of a transmitter which amplifies and modulates the signal and a receiver system which feeds the signal into the mixer circuits to enable frequency conversion and demodulation. An oscillator is a circuit that generates a repetitive waveform, ..

From Threaded to Quick The technology for RF threaded connectors began in the early days of UHF communications and, since that time, other RF connectors have been developed to meet the needs of advancing technologies in the communications industry. In the early 1990’s, RF manufactures needed RF cable assemblies with interconnects that could manage the ..

Who dares thwart the power of Zeus? Surge protectors and lightning arrestors are devices that protect electrical components from a temporary rise in voltage and current on an electrical circuit.  Surge protectors are designed to protect electronic equipment from power surges and voltage spikes by diverting the excess current from the transient event or surge ..

Many coaxial cable and connector types are available in the RF and microwave industry designed for specific purposes and applications; compatibility with other RF microwave components is achieved with universally accepted cable and connector standards. The US Department of Defense (DOD) develops standards for materials, facilities, engineering, and testing practices in order to improve military ..

Increasing reliance on electronic devices for industrial, aerospace, and military applications compels manufacturers of RF/microwave cable assemblies to offer cables that exhibit high reliability in many types of environments and operating conditions. Some areas of applications that require Hi-Rel components include space, military and defense, test and measurement, wireless mobile communications, automotive, medical, and other ..

Introduction In the previous blog, Part 1 of “RF Interconnect Insights for High Speed Digital Signals and Data Communications” two part series, the concept of RF interconnect used in high speed digital applications was introduced. In this section, more insights will be provided on intermodulation distortion concerns and other challenges with trends in high speed ..

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 ..
