11303-3 is a low-profile 3dB hybrid coupler that features an easy-to-use surface-mount package and covers the NMT 450 frequency band. 11303-3 is an ideal choice for balanced amplifiers and signal distribution, 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 that are compatible with common substrates (such as FR4, G-10, and polyamide).
