Check rf 100 receiver.
RF tags use wireless technology. Radio or wireless is a way of transmitting energy through empty space—that is, instead of using a wire cable. The energy is carried by invisible waves of electricity and magnetism that vibrate through the air at the speed of light. The basic science and the practical technology of wireless communication was developed in the second half of the 19th century.

The analog output on the receiver module (Received Signal Strength Indicator (RSSI) pin 3) can be connected to an ADC and used as a rough indicator of signal strength whenever the receiver is locked on an RF signal. To be useful, it needs to be read only during signal transmissions. When there is no signal present it will still be a bit high.Channel selection in a receiver. First, the band is selected, and then the channel is selected. Channels are very close to each other hence. high Q filter is required to select a channel; however, it is unlikely to design so high Q filters in high frequency for choosing the desired channel. So first, the down conversion is done to bring down ...

RF Receiver Architecture. An RF receiver typically consists of four main blocks: the antenna, the RF amplifier, the mixer, and the demodulator. The antenna is used to receive the RF signal and convert it to an electrical signal. The RF amplifier is used to amplify the signal before it is mixed with a local oscillator (LO) signal in the mixer.
Test setup for receiver sensitivity measurement. The figure-1 depicts test setup used for RF Receiver sensitivity measurement. Following equipments or tools are used for the measurement: -120dBm at BER of 10 -6. This is usually specified for example in VSAT RF Transceiver or other RF devices. Do the test setup as shown in the figure.1. Reset receiver by simultaneously pressing the LEARN & OVERRIDE button for 4 seconds. 2. Press and release the LEARN button. This sets the receiver to the learn mode. 3. Press and release the LEARN button on the back of the transmitter. 4.
