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

Amplifiers
Instead of cascading a set of narrowband amps, use a single amplifier from Keysight and enjoy ultrabroad bandwidths - like 0.01 to 26.5 GHz, 0.045 to 50 GHz, and ranges in between. But the best thing about Keysight broadband amplifiers is what they eliminate and reduce: noise, crossover networks, and multiple power supplies.
