Description
The 1F1304-3S is a low profile 3dB hybrid coupler in an easy to use surface
mount package covering 470 to 860 MHz. The 1F1304-3S is ideal for
balanced amplifiers and signal distribution and can be used in most high
power designs. Parts have been subjected to rigorous qualification testing
and units are 100% tested. They are manufactured using materials with x
and y thermal expansion coefficients compatible with common substrates
such as FR4, G-10 and polyimide. Available in both 5 of 6 tin lead (1F1304-
3) and 6 of 6 tin immersion (1F1304-3S) RoHS compliant finishes.
