Dual Directional Couplers & Load Attenuators

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

CouplersCover 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. This broad range gives you flexibility in coupling low-and high-power amps to power meters, spectrum analyzers, receivers, oscilloscopes, and other sensitive measuring instruments.

Dual directional design- two couplers in the same package—lets you monitor forward and reflected power. The directivity, flatness and coupling factors are excellent, allowing for accurate measurement of power..

Dual directional couplers are required for measurements per IEC 61000-4-3 and -6. Popular applications include power sampling, amplifier leveling, VSWR monitoring, field control and amplifier load protection.

All AR couplers are power- and frequency-matched to our amplifiers and antennas.

Load AttenuatorsLA 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.
