That depends (since there isn’t enough information here to do anything with.) Do you want just the chip (which is the data sheet you posted, or the module in the picture. If it is the module you want a google search of the form “fritzing part Si4432 module” turns up one here
although it doen’t appear to be the same as the picture. If you want that particular module you would need to provide a web site which contains the physical dimensions of the board and the connector information,.
