Abstract :
Tests were conducted to find a suitable means for connecting up to eight 250 watt, 150 MC base station transmitters to a common antenna. Terminated circulators and RF hybrids were employed for isolating and combining the transmitters. A practical circuit was developed and an eight transmitter multiplex system is now in commercial service.
