The ADF7011 is a low power OOK/ASK/FSK/GFSK UHF transmitter designed for use in ISM band systems. It contains an integrated VCO and Σ-∆ fractional-N PLL. The output power, channel spacing, and output frequency can be programmed with four 24-bit registers.
The ADF7011 is a single‑chip, low‑power UHF transmitter designed for ISM‑band systems. It integrates a VCO and fractional‑N PLL, offering programmable output power, channel spacing, and frequency via four 24‑bit registers. The device supports OOK, ASK, FSK and GFSK modulation schemes and operates from a 2.3 V to 3.6 V supply.
The datasheet provides detailed specifications, pin configurations, timing characteristics, absolute maximum ratings, and ordering information for the 24‑lead TSSOP package. It also includes performance graphs and typical application notes for wireless data transfer, remote control, and keyless entry.
