| | | | ◊ Đặc điểm chính: | | RFM66W ISM TRANSCEIVER MODULE v1.0 868 & 915MHz Ultra Low Power High Link Budget Integrated UHF Transceiver
GENERAL DESCRIPTION
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.

General Description
The RFM66W is a single-chip integrated circuit ideally suited for today's high performance ISM band RF applications. The RFM66W's advanced feature set includes a state-of-the-art packet engine and top level sequencer. In conjunction with a 64 byte FIFO, these automate the entire process of packet transmission, reception and acknowledgement without incurring the consumption penalty common to many transceivers that feature an on-chip MCU. Being easily configurable, it greatly simplifies system design and reduces external MCU workload to an absolute minimum. The high level of integration reduces the external BoM to passive decoupling and impedance matching components. It is intended for use as a high- performance, low-cost FSK and OOK RF transceiver for robust, frequency agile, half-duplex, bi-directional RF links. Where stable and constant RF performance is required over the full operating range of the device down to 1.8V the receiver and PA are fully regulated. For transmit intensive applications - a high efficiency PA can be selected to optimize the current consumption. The RFM66W is intended for applications requiring high sensitivity and low receive current. Coupling the digital state machine with an RF front end capable of delivering a link budget of 143dB (-123dBm sensitivity in conjunction with +20dBm Pout). The RFM66W complies with both ETSI and FCC regulatory requirements and is available in a 5 x 5 mm QFN 24 lead package. The low-IF architecture of the RFM66W is well suited for low modulation index and narrow band operation.
