RF Transceiver Module RFM69CW 868 MHZ
The RFM69CW is a transceiver module capable of operation over a wide frequency range, including the
868MHz license-free ISM (Industry Scientific and Medical) frequency bands. All major RF communication parameters are programmable and most of them can be dynamically set. The RFM69CW offers
the unique advantage of programmable narrow-band and wide-band communication modes The RFM69CW is optimized for low power consumption while offering high RF output power and channelized operation. Compliance ETSI and FCC regulations. In order to better use RFM69CW modules, this specification also involves a large number of the parameters and functions of its core chip RF69's, including those IC pins which are not led out. All of these can help customers gain a better understanding of the performance of RFM69CW modules, and enhance the application skills.

Receiver:
All receiver tests are performed withRxBw= 10 kHz (Single Side Bandwidth) as programmed inRegRxBw, receiving a PN15 sequence with a BER of 0.1% (Bit Synchronizer is enabled), unless otherwise specified. The LNA impedance is set to 200 Ohms, by setting bitLnaZininRegLnato 1. Blocking tests are performed with an unmodulated interferer. The wanted signal power for the Blocking Immunity, ACR, IIP2, IIP3 and AMR tests is set 3 dB above the nominal sensitivity level.
