A COMPACT LINE of magnetron pulse modulators has been spawned to replace tube-based pulsers for highpower- radar transmitters delivering peak RF powers of 3 to 50 kW. The DTI PowerMod solid-state pulse modulators provide over 99 percent switching efficiency. Depending upon load, pulse frequencies range up to 100 kHz. The modulators feature adjustable pulse widths from sub-microseconds to DC pulse to pulse. Under typical performance, the modules vow to reduce arc-energy to fractions of a joule. They extend magnetron transmitter life up to 50,000 hrs. mean time between failure (MTBF). Suitable for driving magnetrons across the L- to Ka-band frequency range, the modulators use standard circuit components and topologies. They measure 10 x 13 x 9 in. with custom configurations available. P&A: $30,000 to $200,000 depending upon system requirements.
