The ADF7012 is a low power FSK/GFSK/OOK/GOOK/ASK UHF transmitter designed for short-range devices (SRDs). The output power, output channels, deviation frequency, and modulation type are programmable by using four, 32-bit registers.
The ADF7012 is a single‑chip, low‑power UHF transmitter that supports multichannel operation across the 75 MHz–1 GHz ISM bands. It offers programmable output power, multiple modulation schemes (FSK, GFSK, OOK, GOOK, ASK), and a 3‑wire serial interface for register configuration. The device includes an on‑board regulator, low‑battery‑voltage indicator, and operates from 2.3 V to 3.6 V.
The datasheet details electrical specifications, pin functions, timing characteristics, absolute maximum ratings, and typical performance graphs. It also provides design tips for loop‑filter design, PA matching, and transmit protocol considerations, helping engineers integrate the ADF7012 into wireless data‑transfer, security, and keyless‑entry applications.

The ADF7012 operates from 75 MHz up to 1 GHz.
It requires a digital supply voltage (DVDD) between 2.3 V and 3.6 V.
The output power can be programmed from –16 dBm to +14 dBm in 0.4 dB steps.
In power‑down the device draws less than 0.1 µA.
