The document provides an overview of RF (radio frequency) modules, which enable wireless communication and consist of various components including transmitters and receivers. It details different types of RF modules such as transmitter, receiver, and transceiver modules, along with their applications in areas like remote control and wireless data transmission. Key characteristics include low power consumption and operational range from 3 to 30 meters.

2. Introduction
① "RADIO FREQUENCY MODULE"
② Wireless Communication
③ For transmission and reception of
radio signals
④ Various types and ranges
⑤ Some can transmit up to 500 feets

3. Wireless Communication
Wireless Communication is type of
communication in which no wire or
cable is used between transmitter and
receiver.
In other words the communication
which is can be done directly from
transmitter to receiver.

4. Basic parts of RF Modules
1. Printed circuit board
2. Transmit circuit or modulator
3. Transmitter antenna
4. Receiving antenna
5. Receiver circuit or demodulator
6. Output device

5. Different RF modules and ranges

6. Types of RF Modules
①Transmitter Module
②Receiver Module
③Transceiver Module
④System on chip Module(SOC)

7. Transmitter & Receiver Module

8. Transmitter Module
•An RF transmitter module is a small PCB
sub-assembly capable of transmitting a
radio wave and modulating that wave to
carry data.
•The transmitter is chosen in such a way
that its output power should be
according to our requirements.

10. Receiver Module
An RF receiver Module is used to
receive the transmitted RF signal
and demodulate it.
 There are two types of receiver
Module:-
1. Tuned RF receiver
2. Super hetro-dyne receiver.

11. Receiver Module

12. Transceiver Module
Transceiver = transmitter + receiver
So basically this type of module consists of
both transmitter and receiver.
It means it can be used for the transmission
and reception as well.
But It can't send and receive the signals
simentaneously or it is called as half duplex.

13. Applications of RF Modules
①Remote control
②Telemetry
③Small range wireless network
④Wireless home security systems
⑤Robot remote control
⑥Wireless data transmission

14. RF characterstics
①Low power (1mW)
②Good operating range (3 to 30 metres)
③Supports data rate up to 2 Mbps
