WT1231H
This product datasheet contains a detailed description of the WT1231H performance and functionality.
1. General Description
The WT1231H is a transceiver module ideally suited for today's high performance ISM band RF applic
ations. It is
intended for use as high-performance, low-cost FSK and OOK RF transceiver for robust frequency agile, half-duplex bi-
directional RF links, and where stable and constant RF performance is required over the full operating range of the
device down to 1.8V.
The WT1231H is intended for applications over a wide frequency range, including the 315MHz,433 MHz,868 MHz
and 915MHz ISM bands. Coupled with a link budget in excess of 140 dB, the advanced system features of the
WT1231H include a 66 byte TX/RX FIFO, configurable automatic packet handler, listen mode, temperature sensor and
configurable DIOs which greatly enhance system flexibility whilst at the same time significantly reducing MCU
requirements.
The WT1231H complies with both ETSI and FCC regulatory requirements and is available
