The DLP-PNF-1000 from Microwave Vision Group is a Near-Field Probe that operates from 10 to 20 GHz. It provides a gain from 6.5 to 8.5 dBi and has a VSWR of less than 1.9:1. This probe has a port-to-port isolation of more than 45 dB and a cross-polar discrimination of over 35 dB. It supports wideband orthomode junction (OMJ) based on an inverted quad-ridge circular waveguide (with external feeding circuits) to provide dual linear polarization for planar near-field testing.
The DLP-PNF-1000 ensures no nulls in the forward radiation pattern and has minimum waveguide cross-section for low backscattering. It is precision-machined with highly reliable RF components, which results in high measurement accuracy. This probe also includes an RF absorber panel and a polarization switch for enhanced functionality. It is available in an Aluminum housing with 3.5 mm (female) connectors.
