GENERAL DESCRIPTION
The YTX1231H is a transceiver module capable of operation
over a wide frequency range, including the 315,433,868 and
915MHz license-free ISM (Industry Scientific and Medical)
frequency bands. All major RF communication parameters
are programmable and most of them can be dynamically
set. The YTX1231H offers the unique advantage of
programmable narrow-band and wide- band communication
modes. The YTX1231H is optimized for low power
consumption while offering high RF output power and
channelized operation. Compliance ETSI and FCC
regulations.
In order to better use YTX1231H modules, this specification
also involves a large number of the parameters and
functions of its core chip YTX1231H's,including those IC pins
which are not leaded out. All of these can help customers
gain a better understanding of the performance of YTX1231H
modules, and enhance the application skills.
