Check rf 100 receiver.
Selecting RF Receivers. Selecting RF receivers requires an understanding of modulation methods such as AM and FM. On-off key (OOK), the simplest form of modulation, consists of turning the signal on or off. Amplitude modulation (AM) causes the baseband signal to vary the amplitude or height of the carrier wave to create the desired information ...

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.The coherer consisted of two metal plates closely spaced with a supply of metal filings. As the RF signal presented itself to the plates, the metal filings adhered to the plates, closing an electrical circuit. This worked quite well for the detection, but once the RF signal was removed, the filings tended to remain attached to the plates.A diode-based power sensor uses high-frequency diodes to rectify the RF signal to a DC voltage signal. Proportional to the amplitude of the RF signal, this voltage is captured near the signal source. Instruments like an RF power meter can measure and scale the DC voltage to reveal desired power measurements. The relation between the DC voltage ...This page of RF Transceiver test procedure describes how to test RF Transceiver.It covers RF Transceiver measurements such as gain, 1dB compression point, spurious, …
