Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz.

The RF-80's were responsible for the daylight operations; the RB-26s for night photography. In June 1952, the 117th was involved in Exercise 'June Primer'. This exercise took place in an area bordered by a line drawn from Cherbourg to Geneva in the east and in the west by the Swiss, Austrian and Russian occupation zone borders.
Motion capture of two pianists' right hands playing the same piece (slow-motion, no-sounds) [1] Two repetitions of a walking sequence recorded using motion capture [2]. Motion capture (sometimes referred as mo-cap or mocap, for short) is the process of recording the movement of objects or people.

An RF switch or microwave switch is a device to route high frequency signals through transmission paths. RF (radio frequency) and microwave switches are used extensively in microwave test systems for signal routing between instruments and devices under test (DUT). Incorporating a switch into a switch matrix system enables you to route signals ...
An RF transmitter module is a small PCB sub-assembly capable of transmitting a radio wave and modulating that wave to carry data. Transmitter modules are usually implemented alongside a microcontroller which will provide data to the module which can be transmitted.
In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. [1] It consists of all the components in the receiver that process the signal at the original incoming radio frequency (RF), before it is converted to ...
An RF connector must not allow external signals into the circuit through electromagnetic interference and capacitive pickup. Mechanically, RF connectors may provide a fastening mechanism ( thread , bayonet , braces, blind mate ) and springs for a low ohmic electric contact while sparing the gold surface, thus allowing very high mating cycles ...
