Dual polarized antenna SP series

radioexternalprobe

Dual Polarized Probes are a solution for wideband for spherical near-field measurement, suitable for FF measurements, calibration and polarization reference. TECHNICAL PERFORMANCE • Dual linear polarization with high on-axis polarization purity and isolation • Mono-mode excitation on a 1:3 bandwidth • Radiation pattern dominated by first-order spherical modes (allowing for first-order probe correction) • Low return loss / VSWR DESIGN • Wideband orthomode junction (OMJ) based on inverted quad-ridge circular waveguide with external feeding circuits, feeding a circular aperture SURFACE TREATMENT • Surtec 650 according to MIL-C 5541E class 3 • Polyurethane paint REPEATABILITY • Stiff and robust mechanical design • Precision machined • Standard MVG circular interface for precision centering • Precision guiding pin for accurate polarization alignment • High reliability RF components DELIVERED DOCUMENTS • Typical performance data (TYMEDA™) • Measured return loss data and port-to-port coupling EQUIPMENT • Mounting flange • Removable absorber plates • Integrated polarization switch (Optional) RELATED SERVICES • Calibration and maintenance (Optional) • Customization (Optional)
