MODEL DC2600A 
MODEL DC2600, M1, M2 
DUAL DIRECTIONAL COUPLER 
10 kHz - 100 MHz, 600 WATTS 
100 MHz - 250 MHz, 300 WATTS

Amplifier Research Model DC2600A is a high power ultra-broadband coupler with excellent 
performance characteristics over a range of more than 14 octaves. This Dual Directional Coupler is a 
convenient means of simultaneously monitoring forward and reverse power in high power systems 
using normal laboratory oscilloscopes, voltmeters, power meters, and spectrum analyzers.  
 
The Model DC2600A is recommended for use with our “A” and “L” series amplifiers, and other 
amplifiers operating within the frequency and power range.
