Diversified component and system supplier MITEQ recently unveiled two frequency doublers. Model SYS2X1428N01U produces a doubled output of +29 dBm from 27.5 to 28.5 GHz with typical input harmonic rejection of 20 dBc. This doubler requires an input level of typically +10 dBm for input signals from 13.75 to 14.25 GHz, +15 VDC at 740 mA, and 15 VDC at 10 mA. In contrast, model MAX2M0714N01U produces +23 dBm from 13.5 to 14.5 GHz with typical input harmonic rejection of 20 dBc. This doubler requires typical input power of +10 dBm for signals from 6.75 to 7.25 GHz, +15 VDC at 350 mA, and 15 VDC at 10 mA. Both frequency doublers are supplied with type "K" female connectors.
