RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Coaxial Connector Descriptions & Drawings

An RF connector is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection. Mechanically they provide a fastening mechanism (thread, bayonet, braces, push pull) and springs for a low ohmic electric contact while sparing the gold surface thus allowing above 1000 reconnects and reducing the insertion force. Research activity in the area of radio-frequency (RF) circuit design has surged in the last decade in direct response to the enormous market demand for inexpensive, high data rate wireless transceivers. - Wikipedia

Maximum Frequency: 1 GHz
Utilized in television cable and antenna applications. 75 Ω characteristic impedance. 3/8-32 coupling thread.
Maximum Frequency: 8.5 GHz
Hermaphroditic, 50 Ω impedance with a slide-on interface.
Maximum Frequency: 8.5 GHz
Hermaphrodite connectors. Used in highly critical laboratory applications at frequencies up to
8.5 GHz.
Maximum Frequency: 12 GHz
Uses an internal gasket to seal out the environment.
N male connector drawing - RF Cafe N female connector drawing - RF Cafe
Maximum Frequency: 10 MHz
Round, press-on connector used for consumer-grade audio and composite video connections. Color coded as follows: red (audio-Right), black or white (audio-Left) and yellow (composite video).
(Sub-Miniature A)
Maximum Frequency: 12 GHz
One of the most commonly used RF/microwave connectors. Standard SMA connectors are designed for interconnects to 12.4 GHz. A good SMA is useable to 18 GHz.
