Dual Directional Couplers & Load Attenuators


AR RF Microwave Accessories


A Wide Range Of Couplers Monitor Forward And Reflected Power To 50 GHz

AR RF / Microwave complements its amplifiers with a matching line of Directional Couplers that cover the RF spectrum from 10 kHz to 50 GHz with power handling capability from 50 to 15.000 Watts continuous, 50.000 Watts peak pulse power.

Dual directional couplers are mostly used for forward and reflected power measurements as required by EN/IEC 61000-4-3 and -6 standards.


LA series Load Attenuators monitor signals at acceptable Levels

This series of high-power, fixed coaxial attenuators is recommended for use with RF power amplifiers that operate in the same frequency and power range as the attenuators. The attenuated output provides a means of monitoring the signal at an acceptable level by sensitive measuring instruments like a spectrum analyzer, power meter or oscilloscope, and permits use of a detector for RF leveling.ing, VSWR monitoring, field control and amplifier load protection.
