Sub-GHz transceiver IC boosts link budget, cuts power
The ADF7030-1 features a sensitive receiver and superior immunity to signal interferences as well as low power modes, including the lowest-available current in sleep mode. The transceiver is aimed at Internet of Things (IoT) devices, smart metering, security and building automation, industrial control, and wireless sensor networks.
The chip supports narrowband and wideband operation across sub-GHz ISM bands and data rates from 0.1 kbps to 300 kbps using 2GFSK modulation. The radio transceiver also supports Wireless M-Bus (WMBUS) and IEEE 802.15.4g-based protocols.
Offering high receiver sensitivity that maximizes link budgets and support for larger cell sizes with a high immunity to interference, the new transceiver also improves system reliability. The ADF7030-1 transceiver features a smart wake mode that provides low overall power consumption enabling long lifetime in battery operated systems while maintaining RF performance. The device can enter a low power sleep mode consuming only 10 nA with memory retained.
It features an on-chip ARM Cortex-M0 radio processor that performs radio control and calibration, including time sequencing that reduces engineering development time. A highly programmable packet handler saves more valuable time by simplifying programming interfaces and code development on the host microprocessor. Comprehensive testing by ADI allows engineers to deploy network settings without spending additional time optimizing settings to maximize performance.
In a 6 × 6 mm, 40-lead, LFCSP, the device is priced at $1.99 (1000). The ADF70301-868EZKIT is $599.00.
