ADF7020 ISM Band Transceiver IC

The ADF7020 is a low power, low-IF transceiver designed for operation in the license-free ISM bands at 433MHz, 868MHz and 915MHz. It is suitable for circuit applications that meet either the European ETSI EN-300-220 or the North American FCC, Part 15.247 and 15.249 regulatory standards. It operates from a 2.3 V to 3.6V power supply with programmable output power from -16 to +13dBm in 0.3dBm steps. Its receiver sensitivity is -117.5dBm at 1kbits/s in FSK mode or -110.5dBm at 9.6kbits/s. Power consumption is 20mA in receive mode and 30mA in transmit mode (+10dBm output).

Other features include on-chip VCO (voltage controlled oscillator), Fractional-N PLL, on-chip 7-bit ADC (analog-to-digital converter), digital received signal strength indication (RSSI), temperature sensor and a patent pending fully automatic AFC loop. This allows the ADF7020 to be used with lower tolerance crystals. Its leakage current is < 1uA in power down mode.

Features and Benefits
  • Operates in the frequency bands: 433 to 464MHz and 862 to 928MHz
  • Implements complete transceiver solutions with few external components. No TR switch required.
  • Supports data rates of 0.3 to 200 kbits/s in FSK mode and 0.3 to 75 kbits/s in ASK mode
  • Operates on a 2.3V to 3.6V power supply with programmable output power from -16 to +13dBm in 0.3dBm steps
  • High Receiver Sensitivity, -117.5dBm at 1kbit/s, and high programmable output power, +13dBm, gives superiorlink margin.
