High-Power Directional Couplers

RLC Electronics’ high-power directional couplers offer accurate coupling (±1 dB), low insertion loss (0.1 to 0.35 dB max) and high directivity (> 14 dB at 18 GHz) in a compact package. These high-power couplers are offered with 500 to 1000 W average power handling up to 18 GHz, as well as 100 W versions up to 40 GHz. The standard units are optimized for 2 octave bandwidths and are available with a choice of coupling values (30, 40 or 50 dB) low intermodulation products.

CABLES & CONNECTORS

Dual-Use Waterproof Ethernet Cables

MilesTek’s IP67, dual-use waterproof cables can be used with IP-rated receptacles for a watertight seal or with standard RJ45 jacks. This design eliminates the need to custom order specialized cables that are IP-rated on one end and have a standard RJ45 connector on the other end. This dual functionality is accomplished by a waterproof shroud that can be pulled back to mate with standard RJ45 jacks. These cable assemblies feature a CMX outdoor burn rating, foil shield to protect against EMI/RFI interference and a tethered dustproof shroud cap.
