Integrated Thin-Film High-Directivity Coupler Series For WiFi Band Applications


AVX has introduced a new series of integrated thin film (ITF), high-directivity, directional couplers for WiFi bands. Utilizing Land Grid Array (LGA) packaging technology, the miniature ITF couplers feature a rugged, inherently low profile construction designed for reliable automatic assembly and exhibit excellent high frequency performance across the WiFi frequency spectrum: 2,400-5,950MHz. Available in 0302, 0402, and 0603 sizes, all of which provide identical electrical performance, the 3W couplers also exhibit high directivity (20dB), low parasitics, exceptional solderability, improved heat dissipation, and self-alignment during reflow.

“Featuring miniature case sizes and a rugged construction, our new, integrated thin film, high directivity couplers were specifically designed to provide excellent broadband performance over the WiFi frequency spectrum,” said Larry Eisenberger, senior marketing application engineer, AVX.

The high-directivity couplers are rated for -40C to +85C operation and feature RoHS-compliance and 100% tin terminations that are compatible with automatic soldering technologies, including: reflow, wave soldering, vapor phase, and manual. Finished parts are 100% tested for electrical parameters and visual characteristics, says the company.
