<\/p>\nThese hybrids use normal FR4 board.
\nThe design published here are on the ‘normal’ FR board. Differences in the board material might effect the results of the design.
\nAlthough I didn\u2019t try several boards, the results were usable.
\nThe first design was a simple hybrid as shown here. It was tested at the Leuven Microwave round-table in 2001. Results are published in the bottom table.<\/p>\n

The second step was a 4-way splitter. The hybrids used here are the same as above. The 2 hybrids are preceded by a Wilkinson divider. On the Wilkinson divider is a 2W smd resistor (made of 2 x 220 Ohms 1.3W). On the hybrid to ground are 50 Ohms 1.3W resistors.![](\"https:\/\/pa3csg.nl\/joomla25\/images\/stories\/rf-constr\/23cmhybrid2.jpg\")
