RF Receivers

RF receivers are IC (integrated circuit) components which provide detection of RF (radio frequency) signals. RF receivers are designed to receive radio signals from other devices. These ICs embedded in PCB modules to provide wireless communications.
RF receivers receive data in frequency given in MHz, for example, 440MHz. Unlike IR communication, this cannot be interrupted. RF receivers also operate on particular voltage ranges, for example, 4.5 to 5.5 V. It is important

What is modulation?
Modulation is a process which prevents loss of the information transmitted by the frequency. When a signal is modulated, it combines the RF signal with higher-frequency wavelength.

What is the ISM band?
ISM (industrial, scientific and medical) bands are radio bands reserved for ISM purposes. There are processes used in ISM which can interfere with RF communications. There are different types of modulation available in RF receivers, such as:
ASK - Amplitude-Shift Keying
FSK - Frequency-Shift Keying
GFSK - Gaussian Frequency-Shift Keying
OOK - On-Off Keying
PSK - Phase-Shift Keying
QAM - Quadrature Amplitude Modulation

Applications for RF Receivers:
Communications
Remote controls
Car alarm systems
Automation
Security and CCTV
Keyless entry systems
RF Receiver ICs come in various packages such as:
QFN
QSOP
SOIC
TSSOP
