Which RF module are you using ? What interface it has (UART ot SPI). If you are using 433Mhz RF modules you con interface Transmitter Tx pin(Dout) to Tx pin of 89C52 & Receiver Rx pin(Din) to Rx pin of 89C52.You need two microcontrollers for your application, one at transmitter side & other at receiver side.
Post your ffurther doubts.
