The Model DC3401/DC3401A is a high power ultra-broadband dual directional couplers with excellent
performance characteristics over a range of more than 15 octaves. This dual directional coupler provides 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
DC3401/DC340A is particularly recommended for use with our "A" and "L" Series amplifiers, our PM2003
Power Meter and other amplifiers operating within the frequency and power range.
With a frequency range of 10kHz to 400MHz, the Model DC3401/DC3401A is particularly well-suited for Bulk
Current Injection (BCI) test applications.
