Wideband coupler features high directivity for wireless systems
AVX Corporation has developed a new wideband directional coupler with high directivity. Based on thin-film multilayer technology, which provides the miniature part with desirable frequency performance and rugged construction for reliable automatic assembly, AVX’s ITF High Directivity LGA coupler features a 0402 chip size, high directivity (20 dB), and a stable coupling factor (24± 2dB) over a broad frequency range (700-2700 MHz). Compatible with several types of high frequency wireless systems, the new coupler is suitable for mobile communications, satellite TV receivers, GPS, vehicle location systems, wireless LANs, and matching networks. AVX’s ITF High-Directivity LGA Couplers feature an inherently low profile, desirable solderability, self-alignment during reflow, efficient heat dissipation, and a power rating of 3 W. Rated for use from -40°C to +85°C, the wideband, high-directivity couplers are also 100 percent tested for electrical parameters and visual characteristics.
