Microwave Techniques has a full line of waveguide calibration kits, used to accurately calibrate Vector Network Analyzer (VNA) systems. Each kit contains the necessary components to fully calibrate VNAs configured for waveguide measurements. Typically, these complete calibration kits are available in waveguide sizes from WR90 to WR2300. Contact our dedicated RF solutions team today to discuss your requirements.
These waveguide calibration kits utilize three impedance standards, with one transmission standard. This assists to fully impact a two port calibration. Precision cal kits are fully compatible with all VNA systems.
Waveguide Calibration Kits: Our Designs
Traditional coaxial calibration kits utilize three impedance standards and one transmission standard to fully effect a full two port calibration. The standards normally used are Short, Open, Load, and a Through connection. This results in the common “SOLT Coaxial Calibration Kit” nomenclature for this kit.
Unlike coaxial kits, where a “calibrated short” and “calibrated open” are readily achievable, waveguide calibration kits utilize Offset Short-Circuit sections to represent these two parameters. The length of the offsets are set as λ/8 and 3λ/8 long. These designs provide a more balanced phase response over the waveguide operating frequency range.
SSL Style
Microwave Techniques also provides a precision waveguide sliding load. This provides optimum performance over the complete waveguide band. Since waveguide flanges mate together, a special through connection is not required. This results in the Short Short Load (SSL) Style Waveguide Calibration Kit.
In addition, Microwave Techniques provides precision waveguide to coaxial transitions. Typically, these display a VSWR of better than 1.15:1 over the complete waveguide band. Additionally, they display better than 1.10:1 over more than 80% of this band. These precision transitions provide for extreme accuracy when measuring low insertion loss devices.
TRL Style
Another calibration kit Microwave Techniques offers is the Thru Reflect Line (TRL) two port calibration kit. This kit utilizes 3 standards to define the calibrated reference plane. Precision waveguide to coaxial transitions are used in conjunction with a “flush” short circuit plate, as well as a precision λ/4 waveguide section. This design provides a balanced phase response over the waveguide operating frequency range.
SSL Waveguide Calibration Kits
Traditional style calibration kit where three impedance standards and one transmission standard are used to create a full two port calibration. Waveguide Calibration Kits use offset short circuits of 1/8 lambda and 3/8 lambda to represent the calibrated open and calibrated short circuit. Microwave Techniques also provides two precision waveguide to Type-N female transitions, and a precision sliding load to provide optimum performance over the full waveguide band.
