11305-3S is a low-profile 3dB hybrid coupler, featuring an easy-to-use surface-mount package and covering the frequency range of 1.0 to 2.0 GHz. 11305-3S is an ideal choice for balanced amplifiers and signal distribution, suitable for most high-power designs. The parts have undergone strict qualification tests, with 100% testing of the units. They are manufactured using materials with x and y thermal expansion coefficients compatible with common substrates (such as FR4, G-10, and polyamide).
