Coaxial Directional Couplers

Precision High Productivity

Features

• High Directivity
• Broadband Operation
• Precision Connectors
• Low VSWR
• High Tracking Accuracy

Description

The 4030 and 4090 series of precision directional couplers are designed to provide high directivity and an accurate sample of forward or reflected power over octave bandwidths or greater. They are primarily intended for laboratory type applications where an extremely stable and rugged device is required.

The couplers, when used singly or in pairs, are ideally suited for high accuracy swept frequency measurements or reflection coefficient and insertion loss. The use of precision couplers has numerous advantages and applications such as when used with network analyzer systems and in power level measurements.

Units are available with either 7mm ¹ or 14mm (MPC14) ² connectors on the mainline with a precision stainless steel type N female connector on the secondary line input.
