Anritsu Introduces W1 Components with Coverage from DC to 110 GHz

October 9, 2018

Anritsu Co. introduces metrology-grade W1 coaxial components designed and manufactured for precision performance and repeatability to 110 GHz. The new W1 connectorized family — comprising a power splitter, power divider, directional coupler and attenuators — removes measurement complexity, reduces measurement setup time and improves accuracy, making them a superior alternative to waveguide-interface solutions.

Unlike solutions based on banded waveguide frequencies that require a waveguide interface, the W1 components are not band limited and support a frequency range from DC to 110 GHz. This frequency coverage eliminates the need to de-embed adapters between native coaxial interface types, removing the need for calibrations between coax to waveguide, resulting in a solution that saves time and money and is more efficient.

Anritsu’s W1 components include a three-resistor power divider, two-resistor power splitter and a set of attenuators that cover DC to 110 GHz, along with a 20 to 110 GHz directional coupler with typical performance down to 110 MHz. The components are designed with W1 connectors (1 mm compatible) intended for broadband scalability and mode-free performance to 110 GHz, yielding improved measurement accuracy and better device under test (DUT) characterization. They are designed to perform with excellent VSWR and low insertion loss.

The high performance of the W1 connectors makes them well-suited for a variety of high frequency designs. They can be used for on-wafer characterization and measurements, to characterize amplifiers and sub components in automotive radar and for instrument calibration and characterization in metrology labs.
