A resistive splitter is probably the easiest, provided you don't mind the insertion loss or need high isolation. If you want to get fancy, look into Pozar's book, Microwave Engineering for more suggestions.

hi,

you have a few variants:
1) 18 ohm resistors
6dB loss but very simple

2) Microstrip - Wilkinson
but u will need at least 4 stages, i built 3 stages and my BW = 200M÷2.5GHz

There is an excellent search function in EDAboard. Searching for wilkinson gives many hits, for example

To mchpddl1

It is easy to buy such a splitter from stores or on the Internet. You need to look for one for satellite TV.
