Mi-Waves’ 938 series frequency multipliers offer broad-band, high efficiency designs that can be used to generate millimeter wave frequencies from lower frequency microwave sources. The Passive Designs use GaAs varactor diodes mounted on a fin line design provides for minimal circuit losses and optimal harmonic generation.
An SMA female input connector is available up to an input frequency of 50 GHz. X2, X3, and most X4 multipliers use only a single multiplier stage. The 938 series multipliers are designed for input power levels from 30 mW to 100 mW. The multipliers are optimized for specific power levels in this range for an input dynamic range of 3 to 4 dB.
These units are used for LO sources, frequency extension of synthesizers, and
CW transmitters. Options such as isolators and filters can be supplied for many specialized applications.
