RF Coaxial Connector Adapters are simply RF Coaxial Connectors with a common internal transmission line and specific coaxial connector types or genders on either end. For instance, some RF Adapters are simply coaxial connector male-to-male or female-to-female adapters, which allows for the interconnection of a male coaxial connector to another male coaxial connector or a ..

A local oscillator (LO) is an electronic oscillator that generates a very narrow bandwidth signal, or tone, with high purity and stability for use in frequency conversion circuits and timing. As the performance of frequency conversion circuits and timing systems are often dependent on the LO performance, the quality of the oscillator and LO electronic ..

Given the stringent timing requirements of 5G network and wireless applications, RF oscillator performance is of increasingly critical importance. Noise and phase noise are among the most significant of these requirements, as these parameters have the greatest impact on communication signal quality and receiver capability. Though noise and phase noise have always been RF oscillator ..

Ultra-sensitive systems depend on receiver components with as low an added noise figure as possible. Any added noise figure in the receiver chain reduces the signal-to-noise (SNR) of the receiver, and is cumulative. Hence, for each component in the receiver chain contributing noise, the noise floor of the receiver raises. A common method to reduce ..

Though 5G comes with many promises of a ubiquitous high-speed experience with dramatically improved performance over 4G systems, there are several necessary upgrades to underlying technology and infrastructure that are necessary to achieve those desired ends. One such area is with timing and synchronization. In order to realize the desired 5G network responsiveness for high ..

There has been an increasing use of RF coaxial connectors, especially microwave and millimeter-wave coaxial connectors, for high-speed digital and precision sensing applications, There are also a growing trend toward highly compact and interconnect dense microwave and millimeter-wave systems, such as multi-input multi-output (MIMO) antennas for 5G and actively electronically scanned array (AESA) radar antennas. ..

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 ..

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 ..

In many applications, a threaded RF connection may be impractical, or even impossible. Some examples include panel, daughter cards, or inserts with many RF connections. In these cases the pitch between the connectors may necessarily be too small for a threaded nut, or the card/assembly may be inserted into a slot where there is no ..
