ADF7025 is a high performance ISM band transceiver IC from Analog Devices. It works in the frequency range of 431MHz-464MHz, 862MHz-870MHz and 902MHz-928MHz. It supports data rates of 9.6kbps to 384kbps, FSK. The operating voltage is 2.3V-3.6V, and the output power can be programmed from -16dBm to +13dBm in 63 steps. The receiver sensitivity is -104.2dBm (38.4kbps), -100dBm (172.8kbps) and -95.8dBm (384kbps). The working current is 19mA (receive mode) and 28mA (transmit mode).
The ADF7025 is a low‑power, highly integrated FSK transceiver designed for operation in the license‑free ISM bands (433 MHz, 862‑870 MHz, 902‑928 MHz). It supports data rates from 9.6 kbps to 384 kbps and offers programmable output power from –16 dBm to +13 dBm.
The device includes an on‑chip VCO, fractional‑N PLL, 7‑bit ADC, temperature sensor, and digital RSSI. It operates from a 2.3 V to 3.6 V supply, with low current consumption in both receive (≈19 mA) and transmit modes (≈14‑28 mA depending on output power).
