Mechanical Specification

Dual Directional Coupler, 70 – 500 MHz 1KW, 40dB

Product Name

Dual Directional Coupler, 70 – 500 MHz 1KW, 40dB P/N : LS-ASS-001

General Description

This Dual Directional Coupler has been designed to cover the 70 ÷ 500MHz band offering high performance in terms of power, directivity, loss and dimension.
The double structure with appropriate port termination permit to have both direct and reflected power outputs with only one device. The internal symmetrical design permit to have the best trade off between power, insertion loss and ports matching.
The component is realized with very loss tangent and dielectric constant stability across wide temperatures, microstrip TC600 (Arlon) substrate of 0.25” total thickness. Body is made with aluminium CNC high precision enclosure with conductive gasket for the optimal EMI performance.
