The TX3H-869.5-10 is an 869.5MHz FM transmitter module with a power output of 450mW nominal. It is a 100% pin-compatible drop-in replacement for the Radiometrix TX1H-151.300-10 and can be used in applications where greater radiated power is desired (for example when space limitations dictate the use of small and inefficient antennas, or for applications where the extra power is permitted). The module will handle raw data rates up to 10kbps.
