The ADF7024 is an ultralow power, integrated transceiver for use in the license-free ISM bands at 433 MHz, 868 MHz, and 915 MHz. Its ease of use and high performance make it suitable for a wide variety of wireless applications. The ADF7024 is suitable for operation under the European ETSI EN 300-220 regulation, the North American FCC Part 15 regulation, and other similar regulatory standards.The ADF7024 can operate under a number of predefined radio profiles. For each radio profile, optimized register settings are provided for the ADF7024 radio. This ensures that the RF communication layer works seamlessly, allowing the user to concentrate on the protocol and system level design and prototyping. The radio profiles cover common data rate and modulation options. There are six radio profiles in total, as shown in Table 1.The ADF7024 operates with a power supply range of 2.2 V to 3.6 V and has very low power consumption in both Tx and Rx modes, enabling long lifetimes in battery-operated systems while maintaining excellent RF performance.The low IF receiver minimizes power consumption and provides excellent sensitivity. The receiver is exceptionally linear and, therefore, is very resilient to the presence of interferers in spectrally noisy environments. The highly efficient transmitter has programmable output power up to 13.5 dBm and automatic power amplifier (PA) ramping to meet transient spurious specifications. The RF synthesizer comprises a voltage controlled oscillator (VCO), a low noise fractional-N phase-locked loop (PLL) and a loop filter, all of which are fully integrated and automatically calibrated. This agile frequency synthesizer facilitates the implementation of frequency-hopping spread spectrum (FHSS) systems.The smart wake mode (SWM) allows the ADF7024 to wake up autonomously from sleep using the internal wake-up timer without intervention from the host processor. This functionality allows carrier sense, packet sniffing, and packet reception while the host processor is in sleep, thereby reducing overall system current consumption.The ADF7024 eases the processing burden of the host processor by integrating the lower layers of a typical communication protocol stack. The host processor can configure the ADF7024 using a simple command-based protocol over a standard 4-wire SPI interface. A single-byte command transitions the radio between states or performs a radio function.A complete wireless solution can be built using a small number of external discrete components and a host processor (typically a microcontroller).For more information, see the ADF7024 Hardware Reference Manual, UG-698, which is only available as part of the ADF7024 design resource package.APPLICATIONS Wireless sensor networks (WSNs) Home and building automation Asset tracking Process and building control Industrial control Internet of Things (IoT)
