Abstract
The unidirectional and low-noise properties of the Cuccia coupler have been combined with the high-power capabilities of all-copper cavities to yield a new stable protective device for a solid-state amplifier for a superpower radar. A prototype LINEATOR has been constructed and tested at 1,295 Mc, with the capability of withstanding at least 50 kw of peak incident power, providing greater than 100 db of isolation to the solid-state amplifier during the pulse. Recovery is automatic and essentially instantaneous, such that during the receiving period, the terminal insertion loss is approximately 0.3 db, with a total effective input noise temperature less than 35° K. The LINEATOR is a passive nonreciprocal electron-beam-type device, similar to a circulator, except with a linear, rather than a circular, configuration. The prototype model was constructed with four ports, three of which are for signal-handling purposes, and one is for initial beam noise removal.
