Product Summary
The NRF401 is a true single chip UHF transceiver designed to operate in the 433MHz ISM (Industrial, Scientific and Medical) frequency band. The NRF401 features Frequency Shift Keying (FSK) modulation and demodulation capability. The NRF401 operates at bit rates up to 20kbit/s. Transmit power can be adjusted to a maximum of 10dBm. Antenna interface is differential and suited for low cost PCB antennas. The NRF401 features a standby mode which makes power saving easy and efficient. The NRF401 operates from a single +3-5V DC supply.
