Antennas are structures or devices used to collect or radiate electromagnetic waves

Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network).

SWR meters are used to measure the standing wave ratio (SWR) in radio equipment.

RF and microwave laminates are used as substrates for radio frequency (RF) and microwave communication systems and electronics.

Coaxial terminators are electrical devices that connect to the ends of coaxial cables to prevent signals from reflecting back when they reach the end of the cable.

RF amplifiers are devices that accept a varying input signal and produce an output signal that varies in the same way, but with larger amplitude.

RF switches route radio frequency signals to particular waveguides.
