The Frequency Doubler 211A is a high-efficiency millimeter-wave frequency multiplier designed for advanced MM-wave and sub-MM systems operating in the WR-3.4 band. Optimized for input frequencies from 135 to 160 GHz, the 211A delivers doubled output frequencies from 270 to 320 GHz with typical conversion efficiency exceeding 20%. Based on ACST’s high-power multiplier technology and balanced circuit configuration, the 211A provides reliable suppression of unwanted harmonics and robust output performance for laboratory instrumentation, radar, imaging, and high-frequency communication applications.
