The example circuit goes immediately from a carefully layed out PCB to RF connectors... So the answer to your question is resoundingly yes, and if you read all the documentation about the IC, you'd see that it clearly provides all the information you need to get the performance it lists in the PDF out of it.
If you want to wire it dead bug style all the better as the wires can be placed far enough apart to avoid stray capacitance, though you'll still have to keep leads short to avoid inductance. Not sure about ground planes without a PCB though.
