Overview
The ADF7012BRUZ-RL7, 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 flexible frequency selection and fast lock times, making it suitable for fast frequency hopping systems. The transmitter supports five selectable modulation schemes and has programmable output power, deviation frequency, and modulation type through four 32-bit registers.
