SX1236 - 137 MHz to 1020 MHz Low Power Bi-Band Transceiver
SX1236
DATASHEET
GENERAL DESCRIPTION
The SX1236 is a fully integrated ISM band transceiver
capable of bi-band operation in most un-licensed bands in
the sub-GHz space 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 set of
internal power amplifiers are provided permitting either fully
regulated - for constant RF performance, or direct supply
connection - for optimal efficiency. This makes SX1236 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 SX1236 sees fast transceiver
start times and demodulation predicated towards low
modulation index and gaussian filtered spectrally efficient
modulation formats.
This device also support high performance (G)FSK modes
for systems including WMBus, IEEE802.15.4g. The SX1236
delivers exceptional phase noise, selectivity, receiver
linearity and IIP3 for significantly lower current consumption
than competing devices.
