A high-power W-band /90-99 GHz/ solid-state transmitter for high duty cycles and wide bandwidth
Abstract
A three-stage W-band solid-state transmitter with high average power was fabricated using two-diode and four-diode IMPATT power combiners. The transmitter can deliver more than 1.89 W of peak output power from the final stage four-diode combiner. In addition, extremely versatile performance is possible with coherent operation at pulsewidths from 0.1-4 microsec and duty cycles from 5-35%. The mechanical tuning bandwidth ranges from 90-99 GHz with up to 1 GHz injection gain within the operating frequency range. This transmitter can be used for a variety of pulse coded millimeter-wave radar applications where digital or chirp coding, and high-average power is required for long-detection ranges and target classification.
