Overview
The ADF7012BRU-REEL, produced by Analog Devices Inc., is a low-power, multichannel ISM band FSK/GFSK/OOK/GOOK/ASK UHF transmitter. This device is designed for short-range devices (SRDs) and operates within the frequency range of 75 MHz to 1 GHz. It features a fractional-N PLL and VCO with an external inductor, allowing for precise frequency selection and fast lock times, making it suitable for fast frequency hopping systems. The transmitter supports five selectable modulation schemes: binary frequency shift keying (FSK), Gaussian frequency shift keying (GFSK), binary on-off keying (OOK), Gaussian on-off keying (GOOK), and amplitude shift keying (ASK).
