Key Features: 

• Frequency extension modules for Benchtop Series VNA

• Filters and Antenna systems measurement, and on-wafer testing

• Up to 2/4 modules can be connected to the Analyzer (depending on ports number)

• Controlled and powered by the Analyzer

• Supporting all the measurement capabilities of the Analyzer

• Calibrating with mechanical kit

• Optional embedded electronic attenuators

The frequency range extension module is used as part of the Benchtop measuring system with the Benchtop Series Vector Network Analyzers (X4220 and X4420) to determine the S-parameters in the frequency range up to 178 GHz. The system is controlled by the Analyzer software. The number of simultaneously operating modules depends on the configuration of the network analyzer used.


The frequency range extension module is a compact device that includes a frequency multiplier for the measured signal, a broadband power amplifier, an optional electronic attenuator, isolators, directional couplers, and frequency converters. Power supply and control boards are also included. The module is powered by the network analyzer. Autonomous operation of the modules is not provided; without connection to the network analyzer, the module cannot be used to carry out measurements.


Optional embedded electronic attenuators adjust the output power in the range up to -35 dB (-40 typ.) to measure the parameters of active devices (amplifiers, low noise amplifier), including compression point in automatic mode. The frequency range extension modules are also available for rectangular waveguides from 53 to 178 GHz.


They support operating with continuous signals and modulated carriers.
