1D1304-6 is a low-configuration 6dB directional coupler, featuring an easy-to-use surface-mount package and covering the AMPS and GSM frequency bands. 1D1304-6 is an ideal choice for inline separation/combination 1 amplifiers and power injection, suitable for most high-power designs. The parts have undergone strict qualification tests and the units are 100% tested. They are manufactured using materials with x and y thermal expansion coefficients compatible with common substrates (such as FR4, G-10, and polyamide).
