LW433DTXM
433.92MHz RF Transmitter Module
Introduction
LW433DTXM is a compact RF module for 433.93 MHz ISM band for US and European markets. It is ideal for remote control applications where low cost and longer range is required. Using a SAW stabilized resonator, the transmitter ensures accurate frequency control for best range performance without any tuning. The transmitter operates from a 1.5V ~ 12V supply, making it ideal for battery-powered applications. Output power and harmonic emissions are easy to control, making FCC and ETSI compliance easy. The low cost SIP package makes LW433DTXM suitable for high volume applications.
