ADF7012BRUZ, developed and manufactured by Analog Devices Inc., is a low-cost RF Transmitter with an integrated frequency synthesizer and baseband modem, operating in the ISM and SRD Frequency bands. It offers multiple supported data rates, transmit power levels, and operation modes, making it suitable for a variety of applications such as remote control, manual measuring and monitoring of environmental conditions, and other short-range wireless data transmission.

Overview

The ADF7012BRUZRF Transmitter is a complete wireless solution containing two independent synthesizers and baseband modems that can operate in the ISM (industrial, scientific, and medical) and SRD (short range device) frequency bands, while supporting the modulation formats of 4-FSK (frequency shift keying), OOK (on/off keying), and ASK (amplitude shift keying). It is especially designed for low power, low data rate communication. The module can achieve up to +11 dBm output power and operates from a 2.0 to 3.6 V DC supply voltage. Its integrated phase-locked loop (PLL) synthesizer and has excellent spectral control providing the user with the choice of frequency tuning accuracy and stability. The device is provided in a 7x7 mm QFN32 package and is designed for top performance and easy integration into a variety of applications.

Working Principle

The ADF7012BRUZRF Transmitter combines a frequency synthesizer and baseband modems. The frequency synthesizer uses phase-locked loop (PLL) technology to generate a desired frequency, while the baseband modems perform modulation and encoding. The frequency synthesizer is based on an integer-N PLL with a programmable loop filter and gain. To achieve the highest frequency accuracy, the PLL utilizes an external clock source and a temperature compensation circuit for stable operation. The baseband modems support the modulation formats of 4-FSK (frequency shift keying), OOK (on/off keying), and ASK (amplitude shift keying), and allow for data rates up to 250 kbps. Additionally, the module supports frequency hopping to provide anti-interference capability.

The ADF7012BRUZRF Transmitter features robust design and is suitable for a wide range of applications. It offers high output power, low power consumption, and supports multiple modulation methods, allowing for easy integration into wireless systems.
