Upgrade to 110GHz on wafer Vector Network Analyzer (VNA) module
The VNA permits the characterisation in 0.1 - 110 GHz frequency domain by measuring the following parameters:
- S prameters (module and phase
- Quality factor
- Frequency of resonance for different pasive circuits
- Radiation characteristics for antenna
- Insertion losses for microwave and milimeter wave devices
Can be deteminate using S parameters the following coeficients:
- reflexion coeficient
- characteristic impedance
- input impedane
- dielectric constant
- relative permittivity εr
- loss tangent tg(δ)
Technical specifications:
- Broadband frequency test set , 0.1 - 110 GHz
- Mux Coupler to On-Wafer Probes Cable
- Flexibility and expandability,
- Calibration Software (CS)
