anyone know a small size balun working around 150MHz? The smallest ones I found is from minicircuits with footprint of 3.8mm by 3.8mm. Any other verndors provide smaller one?

This is for small signal applications.

you could do a lumped element balun with 0402 components. You could also make an active balun with a single bipolar transistor and an emitter and collector resistor.
