RF Transceiver Module in 868 MHz
Part No : RDM-A8FZ
The RDM-A8FZ is a very low power, high performance, highly integrated FSK/GFSK/OOK/MSK/GMSK transceiver designed for operation in the frequency band 850MHz to 870MHz. Data rates from 1kbps to 300kbps are supported.



The transmitter output power is programmable from −20 dBm to +13.5 dBm, with automatic PA ramping to meet transient spurious specifications. The receiver is exceptionally linear, achieving an IP3 specification of −12.2 dBm and −11.5 dBm at maximum gain and minimum gain, respectively. The RDM-A8FZ operates with a power supply range of 1.8 V to 3.6 V and has very low power consumption in both Tx and Rx modes enabling long lifetimes in battery operated systems while maintaining excellent RF performance. The communications processor, which is custom RISC, 8-bit processor, performs the radio control, packet handling and smart wake mode (SWM) functionality.
