Frequency Multipliers (WR and D Series)


VDI offers a broad range of millimeter-wave varistor mode, passive frequency multiplers based on planar GaAs Schottky diode technology. Frequency doublers and triplers are used to extend the frequency coverage of microwave and millimeter-wave sources. 
Broadband Multipliers 
VDI broadband doublers and triplers have high efficiency (up to ~4%) across full waveguide bands. VDI offers broadband frequency doublers from WR-15 (50-75 GHz) to WR-1.9 (400-600 GHz). VDI offers broadband frequency triplers from WR-15 (50-75 GHz) to WR-0.34 (2200-3300 GHz).  
High Power Multipliers  
VDI high power doublers offer high efficiency (up to ~40%) across a narrowband (~5-10% fractional 3 dB bandwidth). VDI offers high power doublers from ~50 GHz to ~500 GHz. High power doublers can be optimized for specific applications. 

Other Frequency Multipliers 
Alternative frequency mutipliers that are optimized for specific applications may be available upon request. Contact VDI for more information.
