VDI Millimeter-Wave Frequency Extension Modules for UXA, PXA, MXA, EXA Signal Analyzers

The N9029AVxx-Series signal analyzer frequency extension modules, available from VDI as the WRxx SAX Series, when paired with the UXA, PXA, MXA, or EXA signal analyzer with Option EXM,  provide high performance broadband down-conversion of millimeter-wave signals in waveguide bands from 50 GHz to 1.1 THz.

These modules offer low conversion loss and excellent noise figure. Standard features include dual operating modes. First, the module can function as a high performance down-converting mixer. The second operating mode functions as a block down-converter with a broadband IF up to 20 GHz. Power to the module is provided via an included external DC power supply. These frequency extenders minimize conversion loss by multiplying and amplifying the LO signal internally, thus taking advantage of the benefits of low harmonic mixing. This architecture also preserves the X-Series precision frequency resolution and low phase noise, extending those qualities into the millimeter and sub-millimeter bands.
