Werbel Microwave designs and fabricates directional couplers in our Whippany New Jersey facility.  Our own designs and math allows for ultra flat coupling responses over very wide bandwidths.

Parts maybe customized with minimal NRE charges.  Products are RoHS and REACH compliant.  For military customers, Lead alloy solder is available on special order.

For custom design to match your fit, form and function, please use our coupler design form.
