The Model DC3401 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 DC3401 is particularly recommended for use with our "A" and L Series amplifiers, our PM2002 Power Meter and other amplifiers operating within the frequency and power range. With a frequency range of 10kHz to 400MHz, the Model DC3401 is particularly well-suited for Bulk Current Injection (BCI) test applications.
