ADF7025 Rev. A is a high-performance ISM band transceiver IC that supports multiple frequency bands and data rates, with low power consumption and integrated features.
The ADF7025 is a low‑power, highly integrated FSK transceiver designed for license‑free ISM bands at 433 MHz, 863‑870 MHz, and 902‑928 MHz. It supports data rates from 9.6 kbps to 384 kbps and can be used in wireless audio/video, remote‑control, metering, keyless entry, and home‑automation applications.
Key features include a programmable output power range of –16 dBm to +13 dBm, an on‑chip VCO with fractional‑N PLL, an integrated 7‑bit ADC and temperature sensor, digital RSSI, and a low‑current zero‑IF receiver architecture. The device operates from a 2.3 V to 3.6 V supply and offers multiple programmable bandwidth and filter options.
