nRF904

nRF904 is a single-chip transmitter for the 902-928 MHz band. It is compliant with the US Federal Communications Commission (FCC) standard CFR47 chapter 15. The transmitter consists of a fully integrated frequency synthesiser, a power amplifier, a crystal oscillator and a modulator. Due to the use of the crystal-oscillator stabilised frequency synthesiser, frequency drift is much lower than in comparable SAWresonator based solutions. Output power and frequency deviation is easily programmable by use of external resistors. Current consumption is very low, only 9 mA at an output power of 10dBm. Built-in Clock and Power Down modes makes power saving easily realisable.
