I/J Band Low-Cost Crossed-Field Amplifier.
Abstract
This program is directed toward development of an I/J band, linear format, injected-beam crossed-field amplifier (IBCFA) for electronic warfare. The IBCFA should be capable of power output of 1000W peak, 200W average, between 8.5 and 17GHz with 20dB gain. A laser-cut shaped-substrate meander line is used. The performance objectives for E/F band CFA's include 3kW peak pulse power output and 1kW average power output, 20dB gain, 2-4GHz, for electronic warfare; and 2kW peak pulse power output at 10-15% duty, 25dB gain, 3.0 to 3.6GHz, for phased-array radar. One E/F band tube has been built. Preliminary tests at 10% duty directed toward electronic warfare applications showed 3kW peak power at midband, 1,5kW at 2GHz, and 2.4kW at 4GHz. Increased drive power leads to greater power output at the low end of the band, indicating the need for greater circuit length. This tube will be tested further for its characteristics in the phased array mode and for full rated duty in the electronic warfare mode. Another E/F band tube is under construction, this one with increased circuit length.
