The LMR 200 Coaxial Cable is a cable that can carry high frequency RF signals with low signal attenuation. It enables easy routing in wireless systems applications and is ideal for use in telecommunication systems.
LMR 200 Coaxial Cable
LMR 200 Coaxial Cable Construction
The LMR 200 is a 50-ohm, low-loss, flexible, double-shielded coaxial cable with an overall diameter of 0.195 inches, developed by Times Microwave Systems, and has a voltage rating of up to 1000 VDC. It has an internal bare copper conductor (carrying the electrical signal), which is enclosed by an insulation layer made of Foam Polyethylene (Foam PE). The insulation layer is then completely enclosed by two shield layers. The first shielding layer is made of aluminum tape, and the outer shield is made of a tinned copper braid. The shields form an outer conductor, which also provides protection from electromagnetic interference (EMI). Finally, the structure is covered with an outermost layer - called a jacket - made of Polyethylene (PE). The jacket protects the cable core from mechanical, moisture, chemical issues, and environmental factors.
The LMR 200 cable exhibits capacitance of approximately 24.5 pF/ft (80.3 pF/m) and signal attenuation of around 9.9 dB/100ft at 900 MHz (signal attenuation of the cable depending on the frequency) and has a velocity of propagation of 83 %. It has a center conductor measuring 0.044 inches (1.12 mm) in diameter and an insulation layer measuring 0.116 inches (2.95 mm) in diameter. The double shielding structure of the LMR 200 coax cable offers RF shielding of more than 90 dB.
The flexible, low-loss LMR 200 cable is ideal for jumper assemblies in wireless communications systems, short antenna feeder runs, and any application (e.g., WLL, GPS, LMR, WLAN, WISP, WiMAX, SCADA, Mobile Antennas) requiring an easily routed, low loss RF cable.
