RFM66W
RFM66W ISM TRANSCEIVER MODULE v1.0
868 & 915MHz Ultra Low Power High Link Budget Integrated UHF Transceiver
GENERAL DESCRIPTION
TAL
The RFM66W is a fully integrated ISM band
transceiver optimized for use in the (EN 300 220-1) 868
MHz band in Europe and the (FCC Part 15) 915 MHz band
in the US with a minimum of external components. It offers
a combination of high link budget and low current
consumption in all operating modes. The 143 dB link
budget is achieved by a low noise CMOS receiver front end
and up to +20 dBm of transmit output power. A pair of
internal power amplifiers are provided permitting either fully
regulated - for constant RF performance, or direct supply
connection - for optimal efficiency. This makes RFM66W
ideal for either M2M applications powered by alkaline
battery chemistries or long battery life metering applications
using Lithium battery chemistries.
The Low-IF architecture of the RFM66W sees fast
transceiver start times and demodulation predicated
towards low modulation index and gaussian filtered
spectrally efficient modulation formats.
