Anritsu has introduced a range of W1 coaxial components that are  designed for high-frequency measurements. 

The W1 range includes a three-resistor power divider, two-resistor power splitter and a set of attenuators that provide coverage from DC to 110GHz, along with a 20-110GHz directional coupler with typical performance down to 110MHz. 

The components are designed with W1 connectors (1.0 mm compatible) intended for broadband scalability and mode-free performance to 110GHz.
