Description
The TRF4903 single-chip solution is an integrated circuit intended for use as a low-cost multiband FSK or OOK transmitter to establish a frequency-programmable, half-duplex RF link.
Features
- a fully-integrated VCO. Only the PLL loop filter is external to the device. Two fully-programmable operation modes, Mode0 and Mode1, allow extremely fast switching between two preprogrammed settings (for example, TX_frequency_0/TX_frequency_1; …) without reprogramming the device. ISM band standards Europe has assigned an unlicensed frequency band of 868 MHz to 870 MHz. This band is specifically defined for short range devices with duty cycles from 0.1% to 100% in several subbands. The new Europe.
