433.92MHz FSK RF Transmitter Module


LW216M is a compact FSK RF transmit module for the 433MHz ISM band. Consisting of a complete local oscillator made of phase locked loop, mixer and power amplifier, it simplifies the OEM’s design and assures successful field operation. The module works with LW116M FSK RF receiver module and also with other standard data decoding/encoding chips to provide seamless and transparent RF communications. LW216M is made to be a drop-in module for seamless integration, easy operation and fast time-to-market.

The module is ideal for short-range remote control applications in which cost is a primary concern. The transmitter module requires no external RF components except for the antenna. It has installed SAW filter at the antenna output to minimized LO emissions. When pairing with LW116M FSK transmitter module, it is suitable for applications in which robust performance is required.
