AVX Corporation has developed a wideband directional coupler with high directivity. Based on thin-film multilayer technology, which provides the miniature part with excellent frequency performance and rugged construction for reliable automatic assembly, the ITF high directivity LGA coupler features a 0402 chip size, high directivity (20 dB), and a stable coupling factor (24 ±2-dB) over a broad frequency range (700 to 2700 MHz).

Compatible with several types of high frequency wireless systems, the coupler is ideal for applications including: mobile communications, satellite TV receivers, GPS, vehicle location systems, wireless LANs, and matching networks.

The ITF high-directivity LGA couplers feature an inherently low profile, excellent solderability, self-alignment during reflow, efficient heat dissipation, and a power rating of 3 W. Featuring lead-free Sn100 nickel/solder coated terminations, the couplers are compatible with automatic soldering technologies, including reflow, wave soldering, vapor phase, and manual. Rated for use from -40° to +85°C, the wideband, high-directivity couplers are also 100% tested for electrical parameters and visual characteristics.
