MODEL DC3400A
MODEL DC3400
DUAL DIRECTIONAL COUPLER
200 WATTS CW
10kHz - 400MHz
The Model DC3400A is a high power ultra-broadband dual directional coupler with excellent
performance characteristics over a range of more than 15 octaves. This dual directional coupler is a
convenient means of simultaneously monitoring forward and reflected power in RF power systems
using normal laboratory oscilloscopes, voltmeters, power meters and spectrum analyzers. The Model
DC3400A is particularly recommended for use with our "A" and “L”Series amplifiers, and other
amplifiers operating within the frequency and power range.
With a Frequency range of 10kHz to 400MHz, the Model DC3400A is particularly well suited for
Bulk Current Injection (BCI) test applications
