ADF7021BCPZ

RF Transceiver ICS Overview

The ADF7021BCPZ is a high-performance, low-power, highly integrated narrowband transceiver supporting 2FSK, 3FSK, 4FSK, and MSK modulation. It operates in license-free ISM bands and licensed frequency ranges of 80 MHz to 650 MHz and 862 MHz to 950 MHz. The device features dual voltage-controlled oscillators (VCOs) with an internal LC tank for higher frequencies and an external inductor option for lower bands, enabling dual-band operation. Key electrical parameters include a maximum data rate of 32.8 kb/s, a transmit output power of 13 dBm, and receive supply current of 17.5 mA. It functions within a supply voltage range of 2.3 V to 3.6 V and supports operating temperatures from -40°C to +85°C.
