Featuring a frequency range of 800-6,000MHz, these 0603 couplers are currently unique in their ability to provide 10W continuous power handling.

AVX has introduced the smallest thin-film 10W 3dB directional couplers available in today’s market. Based on AVX’s thin-film technology, the new 0603 3 dB 90° couplers exhibit excellent high-frequency performance in ranges spanning 800-6,000MHz and are currently unique in their ability to provide 10W continuous power handling.

“Although designed for use in a wide variety of wireless communications applications, the power handling capabilities, expansive frequency range, and miniature size of our new thin-film 10W 3dB couplers makes them especially attractive for portable communications devices,” said Larry Eisenberger, senior marketing application engineer at AVX.

Utilising Land Grid Array (LGA) packaging technology, the directional couplers feature an inherently low profile, low parasitics, excellent solderability, and improved heat dissipation in addition to self-alignment during reflow. Surface mountable and RoHS compliant, the DB0603N couplers also feature low loss, high isolation, and rugged construction for reliable automatic assembly. Use them in wireless communications applications, including: mobile communications, satellite TV, GPS devices, vehicle location systems, and wireless LANs, among others.
