Product Summary

The TRF6900APT is a Single-Chip RF Transceiver which is an integrated circuit intended for use as a low cost FSK transceiver to establish a frequency-agile, half-duplex, bidirectional RF link. The device is available in a 48-lead TQFP package and is designed to provide a fully-functional multichannel FM transceiver. The chip is intended for linear (FM) or digital (FSK) modulated applications in the new 868-MHz European band and the North American 915-MHz ISM band. The single chip transceiver operates down to 2.2 V and is expressly designed for low power consumption. The synthesizer has a typical channel spacing of approximately 230 Hz to allow narrow-band as well as wide-band application. Due to the narrow channel spacing of the direct digital synthesizer (DDS), the DDS can be used to adjust the TX/RX frequency and allows the use of inexpensive reference crystals.
