How to connect 2mm surface mount component to 2.54mm breadboard
You'd need to build a board which breaks out these pins to 0.1" pitch headers.  That said, think about what you're connecting: An RF module!  The datasheet reads: 


  It needs only an MCU, crystal, decoupling capacitor and antenna to build a high reliability FSK transmitter.


The MCU will communicate over SPI with the module, and there are also interrupt, valid data, and reset pins.  Those are reasonably low-speed, strongly-driven logic pins, and are probably fine on a breadboard.  However, you still need to provide the module with some heavier decoupling than the 0402 caps on the module (which are probably only 10 or 47 nF), and with an ANTENNA.

I'd suggest a breakout board (toner transfer or professional, you decide) with a low-impedance 0.1 uF ceramic cap as well as a larger 10, 22, or 47 uF tantalum or ceramic tank capacitor as near the module as you can get it.  Running the single Positive Power Supply pin through a breakout board or wire, into a header pin, down to  the breadboard (shudder), to some through-hole electrolytic, and thence through more breadboard connections and a long wire into a lab power supply simply won't give this module the clean power it needs.  Put decoupling on the breakout board, and you'll be much better off.

Probably most importantly, you need an antenna.  Don't even think about trying to connect the antenna through the breadboard, that's just silly.  Put an SMA connector, chip antenna, or PCB antenna on your breakout board.

Finally, break out the module pins that are going to the breadboard  (you'll need 9 to connect all the pins, or a minimum of 5) to a 0.1" header.  You can either use through-hole headers in a DIP format (which will provide some necessary sturdiness if you use an SMA antenna) or solder the header to the edge (which will place a PCB strip antenna vertically, which is probably a good thing).
