1F1304-3S is a low-configuration 3dB hybrid coupler, featuring an easy-to-use surface-mount package and covering the frequency range of 470 to 860 MHz. 1F1304-3S 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% unit testing. 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. 5/6 tin-lead (1F1304-3) and 6/6 tin-lead (1F1304-3S) RoHS-compliant finishes are provided.
