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.

2. Electrical Characteristics
2.1. ESD Notice
The RFM66W is a high performance radio frequency device. It satisfies:
Class 2 of the JEDEC standard JESD22-A114-B (Human Body Model) on all pins.
Class III of the JEDEC standard JESD22-C101C (Charged Device Model) on all pins
It should thus be handled with all the necessary ESD precautions to avoid any permanent damage.
2.2. Absolute Maximum Ratings
Stresses above the values listed below may cause permanent device failure. Exposure to absolute maximum ratings for
extended periods may affect device reliability.
