Current consumption

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.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.
