Miniature wideband coupler offer 20dB of directivity for wireless applications
June 25, 2012 // Julien Happich
AVX's ITF High Directivity LGA coupler features a 0402 chip size, high directivity (20dB), and a stable coupling factor (24±2dB) over a broad frequency range (700-2700MHz).
Compatible with several types of high frequency wireless systems, the new coupler is suitable for applications including: mobile communications, satellite TV receivers, GPS, vehicle location systems, wireless LANs, and matching networks. The couplers feature an inherently low profile, excellent solderability, self-alignment during reflow, efficient heat dissipation, and a power rating of 3W. Featuring lead-free Sn100 nickel/solder coated terminations, the new 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.
