Power Dividers & Combiner Product List

POWER DIVIDERS & COUPLERS


API Technologies offers an extensive line of quadrature hybrid and directional couplers including:

These couplers feature low loss, high directivity and low flatness and are designed to meet MIL-E-5400 Class 3. All couplers are available as standard parts or can be customized with a variety of options including customized frequency bands & optimization, mounting schemes, screening and testing upgrades.

API Technologies Power Dividers are designed with high isolation and exceptional phase balance in mind. Our Wilkinson style power dividers yield superior isolation between the output ports. Stripline and microstrip styles can be produced without the high cost of lumped inductors or capacitive elements. We offer a wide variety of customization options to suit your application.
