ADF7021-V is a high performance, low power, narrow-band transceiver IC that integrates frequency synthesizer, filter, power amplifier, demodulator, coder, etc. The frequency range is 80MHz-960MHz, and the external VCO is used. The output power, IF filter bandwidth, modulation method, etc. can be configured.
The ADF7021‑V is a narrow‑band RF transceiver IC that uses an external voltage‑controlled oscillator (VCO) to achieve low phase‑noise performance across 80 MHz to 960 MHz. It supports multiple modulation schemes (2FSK, 3FSK, 4FSK, MSK) and offers programmable IF filter bandwidths of 9 kHz, 13.5 kHz, and 18.5 kHz.
The device operates from a 2.3 V to 3.6 V supply, provides programmable output power from –16 dBm to +13 dBm in 63 steps, and includes on‑chip ADC, temperature sensor, RSSI, and an automatic frequency‑control loop. Detailed register maps and pin descriptions enable integration with microcontrollers or DSPs.
