A coherent distributed two-element radiofrequency (RF) transmitter implemented with wireless clock transfer is presented in this letter. This work represents the first demonstration, to the authors' knowledge, of a distributed RF transmitter using one-way wireless clock transfer, where the slave node need not provide any information to the master node. Two 1-GHz transmitters were implemented and coherent gain above 90% of ideal signal summation was achieved with a probability of 0.97. Experimental results show near-ideal 6-dB gain from the two-transmitter system at a distance of 85 m.
