Pasternack has expanded its line of 50 Ω coaxial probes to 40 GHz, extending the capability to measure microwave components and signal integrity in high speed communications and networking equipment. With this frequency extension, Pasternack adds four models to its line of coaxial RF probes, providing ground-signal (GS) and ground-signal-ground (GSG) configurations (two models each), with 800 or 1500 μm pitch (two models each). All have a 2.92 mm coaxial interface and have less than 0.5 dB insertion loss and better than 10 dB return loss-typically 20 dB-over the broad range from DC to 40 GHz.
Gold plated, the probes have compliant pogo pin contacts, enabling a wide range of probing angles. They can be used manually with a coaxial cable assembly or with Pasternack’s probe positioner. A pair of coaxial GSG probes can be used with delay matched cable assemblies to perform high speed differential measurements. The 40 GHz probes support a wide range of measurement needs: signal integrity, MMIC evaluation, Gigabit SERDES, 28 Gbps data channels, substrate characterization, coplanar waveguide circuits and test fixture applications.
Pasternack’s new 40 GHz coaxial RF probes are in stock, ready for immediate shipment with no minimum order quantity.
