TRF6903

The TRF6903 single-chip solution is an integrated circuit intended for use as a low-cost multiband FSK or OOK transceiver to establish a frequency-programmable, half-duplex, bidirectional RF link. The multichannel transceiver is intended for digital (FSK, OOK) modulated applications in the North American and European 315-MHz, 433-MHz, 868-MHz, and 915-MHz ISM bands. The single-chip transceiver TRF6903 operates down to 2.2 V and is designed for low power consumption. The synthesizer of TRF6903 has a typical channel spacing of better than 200 kHz and 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,  receive (RX)/transmit (TX); TX_frequency_0/TX_frequency_1;  RX_frequency_0/RX_frequency_1; .) without reprogramming the TRF6903.
