2. Common base - Wikipedia

   en.wikipedia.org/wiki/Common_base

   For R S values in the vicinity of r E the amplifier is transitional between voltage amplifier and current buffer. For R S ≫ r E the driver representation as a Thévenin source should be replaced by representation with a Norton source. The common base circuit stops behaving like a voltage amplifier and behaves like a current follower, as ...

3. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

   A double DIN 1.6/5.6 bulkhead jack connector, crimp type, for 75 Ω coaxial cable A Type N connector (male), right-angled solder-type for semi-rigid coaxial cable with a diameter of 0.141-inch. 4.1-9.5 connector, standardized as DIN 47231 (in 1974) and IEC 60169-11 (in 1977) 4.3-10 connector, formerly known as DIN 4.3/10, now standardized as ...

5. N connector - Wikipedia

   en.wikipedia.org/wiki/N_connector

   The male connector is hand-tightened (though versions with a hex nut are also available) and has an air gap between the center and outer conductors. The coupling has a ⅝-24 UNEF thread . Amphenol suggests tightening to a torque of 15 inch-pounds (1.7 N⋅m), [ 2 ] while Andrew Corporation suggest 20 inch-pounds (2.3 N⋅m) for their hex nut ...

   Various popular RF connectors Electronic symbols for the plug and jack coaxial connectors Time-domain reflectometry shows reflections due to impedance variations in mated RF connectors. An RF connector (radio frequency connector) is an electrical connector designed to work at radio frequencies in the multi-megahertz range.

7. Klystron - Wikipedia

   en.wikipedia.org/wiki/Klystron

   The simplest klystron tube is the two-cavity klystron. In this tube there are two microwave cavity resonators, the "catcher" and the "buncher". When used as an amplifier, the weak microwave signal to be amplified is applied to the buncher cavity through a coaxial cable or waveguide, and the amplified signal is extracted from the catcher cavity.
