Hybrid Couplers
3 dB, 90
Description
The 11305-3 is a low profile 3dB hybrid coupler in an easy to use surface
mount package covering 1.0 to 2.0 GHz. The 11305-3 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 polyamide.
