UHF FM Data Transmitter


The TX3A & RX3A are miniature UHF radio transmitter & receiver modules designed for PCB mounting. They facilitate the simple implementation of data links at speeds up to 64kbps and distances.. Available for operation in the 868-870MHz band in Europe and the 902-928MHz band in North America, both modules combine full screening with internal filtering to ensure EMC compliance by minimising spurious radiation and susceptibility.
