A resistive type is going to provide little isolation by design - even with ideal components it just wont pull it off. What you need for high isolation is something like a Wilkinson power combiner/splitter. This requires one resistor (100 ohm in the case of 50 ohm transmission lines) and a number of transmission line sections of various impedance. If space is an issue, you can also do it with inductors and capacitors (done on chip sometimes).

hm, ok, although the mini-circ connectorized ones are a bit pricey there are SMD splitters with good specs for about 10eur/pcs. maybe that's the way to go, e.g.
