Variable Coupler: 60-100 dB Ranges
ARRA Variable Directional Couplers are ideal for applications requiring large dynamic attenuated output from the secondary line with minimum main line loss. These units are particularly useful in amplitude monitoring loops, AGC loops and mixer applications.
As in all directional couplers, the main line is isolated from the attenuated secondary line. This type of device can withstand extremely high power levels and may be utilized as a high power continuously variable attenuator with the appropriate termination on the main line output.
