1E1305-3 is a slim 3dB hybrid coupler that features an easy-to-use surface-mount package and covers the PDC bandwidth in Japan. 1E1305-3 is an ideal choice for balanced amplifiers and signal distribution, suitable for most high-power designs. The components 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 that are compatible with common substrates (such as FR4, G-10, and polyamide).
