DUAL DIRECTIONAL COUPLER
3500 WATTS CW
10 kHz - 220 MHz
Amplifier Research Model DC2035 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, powermeters, and spectrum analyzers. Model
DC2035 is recommended for use with our “A” and “L” series amplifiers and other amplifiers operating
within the frequency and power range.
