High Performance, Narrow-Band Transceiver IC
ADF7021-V
FEATURES
High performance, low power, narrow-band transceiver Enhanced performance ADF7021-N with external VCO Frequency bands using external VCO: 80 MHz to 960 MHz Improved adjacent channel power (ACP) and adjacent
channel rejection (ACR) compared with the ADF7021-N Programmable IF filter bandwidths: 9 kHz, 13.5 kHz,
and 18.5 kHz Modulation schemes: 2FSK, 3FSK, 4FSK, MSK Spectral shaping: Gaussian and raised cosine filtering Data rates: 0.05 kbps to 24 kbps Power supply: 2.3 V to 3.6 V Programmable output power: −16 dBm to +13 dBm
