The STE-SF415-15-S1 from Sage Millimeter is a frequency extender/multiplier that upconverts an input frequency from 12.5 to 18.75 GHz to an output frequency of 50 to 75 GHz (4x). The output signal can have a power up to 15 dBm. The frequency extender/multiplier requires a supply voltage of 8 V. The extender is designed as a benchtop unit to extend the low frequency synthesizer or sweeper without losing all of the functionalities and features. The extender also features adjustable legs, which can be removed, to allow for an easy test set up. It is ideal for use in the lab for ATE, network analyzer systems and a number of other applications. It has a WR-15 waveguide interface.
