The JP506S is a slim 6dB directional coupler that features an easy-to-use surface-mount package and is compatible with WCDMA and other 3G applications. The JP506S is an ideal choice for inline split/combine amplifiers for power injection and can be used in most high-power designs. The parts have undergone strict qualification tests and 100% of the units have been tested. They are manufactured using materials with x and y thermal expansion coefficients, which are compatible with common substrates such as FR4, G-10, and polyimide.
