RF mixers are frequency conversion devices that are composed of nonlinear elements that allow for frequency “mixing” of RF, intermediate frequency (IF), and local oscillator (LO) signals. There are two main functions of RF mixers: either upconversion or...
Waveguides are some of the highest performing interconnect and passive components that can be used in RF systems. A waveguide efficiently transfers RF signal energy in a given band and can often handle extremely high-power levels due to a waveguide’s mostly conductive...
A waveguide termination, or waveguide load, is a common waveguide component found in many RF systems, including radar, test & measurement, satellite communications, and aerospace communications. Similar to how RF coaxial terminations work, waveguide terminations...
A waveguide horn, or waveguide horn antenna, is an aperture antenna that uses a gradient transition of the conductive inner wall of the waveguide to the end of the horn in such a way that the waveguide port undergoes an impedance transition that matches with free...
The diversity of RF and wireless applications has driven the diversity of RF coaxial connectors. For essentially all RF applications, there is an RF coaxial connector. It is impossible to cover everything about RF coaxial connectors in a single blog, let alone a book....
The Fairview The RF Cable Designer™ is an extremely useful tool for ordering custom coaxial cable assemblies. Instead of having to email or call a technical sales representative to order a specific custom cable assembly, a user can now simply input their desired...
A RF switch is a basic building block of many RF circuits used in communication, sensing, and test & measurement applications. RF switches are used whenever a signal path needs to be optionally opened/closed, or when specific signal paths need to be selected. An...
A RF Coaxial Hybrid Coupler is a type of RF coupler that essentially behaves as an equal power splitter while also creating a phase shift between the two ports. RF hybrid couplers are generally distinguished by the degree of the phase shift, be it 0 (no phase shift...
RF terminations are one of the most common RF components used in nearly every application and use case where RF systems are employed. An RF termination is simply a terminating impedance that is designed to match the impedance of the transmission line or waveguide used...
Directional RF Coupler A directional coupler is a type of RF coupler that draws a small amount of energy away from the forward and/or reverse signal paths equally. As such, a RF directional coupler is a 4-port passive component with port 1 being the main input port,...
