I need an RF transceiver for which I plan to use an Rx module and Tx Module separately and connect to the same UART.
1)Can both the modules be connected to a single external antenna.
2)Will the Rx module receive whatever is transmitted from the Tx module.
Is there a low cost single transceiver module which can be substituted?

Hi
Most low frequency RF transceiver works in Half duplex mode (transmit or receive)
so, Yes you can connect them to the same antenna
No , In half duplex mode only one side work is working (transmit or receive not both )
All the best

Yup you can connect both of them to the same antenna.
There is a cheap RF transceiver RF12 which cost just $8, which consists of both transmitter and receiver in a single module.
Mostly USARTs are the type that if it is transmitting it will not receive in microcontrollers.
Depends upon MCU..
