Model 100 line. In addition to the above, Tandy produced the TRS-80 Model 100 series of laptop computers. This series comprised the TRS-80 Model 100, Tandy 102, Tandy 200 and Tandy 600. The Model 100 was designed by the Japanese company Kyocera with software written by Microsoft.
Design. Color-coded PS/2 connection ports (purple for keyboards and green for mice) on the rear of a personal computer. An S-video connector: because this is a female connector, Pin 1 is at lower right. Mini-DIN connectors are 9.5 millimetres ( ⁄8 in) in diameter and come in seven patterns, with the number of pins from three to nine.
SMA ( SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism. The connector has a 50 Ω impedance. [ 1] SMA was originally designed for use from DC (0 Hz) to 12 GHz, however this has been extended over time and ...
RF connector. 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. RF connectors are typically used with coaxial cables and are designed to maintain the shielding ...
Mini-BNC connector; Mini-UHF connector, a smaller and much newer design than the standard UHF; SMA connector A 50 ohm screwed connection. The 0.9mm centre pin is the same diameter as the centre of RG402 Coax so that connections to that cable can be made with no discontinuity, forming the pin from the coax itself. Good to 18 GHz
RG-58. RG-58/U is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System. There are several versions covering the differences in core ...
The first Ethernet standard, known as 10BASE5 (ThickNet) in the family of IEEE 802.3, specified baseband operation over 50 ohm coaxial cable, which remained the principal medium into the 1980s, when 10BASE2 (ThinNet) coax replaced it in deployments in the 1980s; both being replaced in the 1990s when thinner, cheaper twisted pair cabling came to dominate the market.
RG-6 coaxial cable for television signals. RG-6 coaxial cable. RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. An RG-6/U coaxial cable has a characteristic impedance of 75 ohms. The term, RG-6, is generic and is applied to a wide variety of cable designs, which differ from one another ...
