Block diagram of a superheterodyne receiver. The RF front end consists of the components on the left colored red. 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]
2.4, 1.85 (sometimes called V) externally similar to SMA but have metric threads and a smaller pin, and do not cross-mate with SMA. The 0.5mm centre pin is the same diameter as the centre of RG405 Coax so that connections can be made with no discontinuity, forming the pin from the coax itself. 1.35 mm connectors, for applications up to 90 GHz
Better models also minimize the change in transmission line impedance at the connection in order to reduce signal reflection and power loss. [1] As the frequency increases, transmission line effects become more important, with small impedance variations from connectors causing the signal to reflect rather than pass through.

Royal Raymond Rife (May 16, 1888 – August 5, 1971) [1] was an American inventor and early exponent of high-magnification time-lapse cine-micrography. [2] [3]Rife is known for his microscopes, which he claimed could observe live microorganisms with a magnification considered impossible for his time, and for an "oscillating beam ray" invention, which he thought could treat various ailments by ...
