11303-3

11303-3 Rev F Hybrid Coupler 3 dB, 90° Description: The 11303-3 is a low profile 3dB hybrid coupler in an easy to use surface mount package covering the NMT 450 band. The 11303-3 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.

The thermal insertion loss is defined in the Power Handling section of the data sheet. As the mounting interface temperature approaches the maximum continuous operating temperature, the power handling decreases to zero 4 11303-3 Rev F Packaging Parts are available in both reel and tube.
