Directional Couplers 500 MHz to 6 GHz by Werbel Microwave

WMDC20-0.5-6.0-X

The WMDC20-0.5-6.0-X series directional couplers cover the continuous band of 500 MHz to 6-GHz with 20 ± 1.0 dB nominal coupling and ± 0.5 dB typical flatness.  The unit is useable to 8 GHz with degradation of performance.  Directivity is 20 dB typical (15 min).  VSWR at all ports is specified 1.3:1 maximum.  Insertion loss is 0.5 typical at the high frequency.  Designed for 100 watts or less.  May be customized with N or SMA female connectors.  Made in Livingston N.J. USA by Werbel Microwave LLC.

MEASURED Main Line VSWR and INSERTION LOSS Response

The main line input and output return loss measurements are displayed in the upper-left and right windows, respectively.  The main line insertion loss is shown in the bottom window.  Markers are placed at the worst-case points, showing a worst-case insertion loss of less than 0.6 dB.

MEASURED COUPLING and DIRECTIONALITY Parameters

In the following screen, the memory trace (lower window) depicts the coupling response.  The directionality parameter is displayed in the upper-left window and measured as reverse isolation, divided by the memorized coupling response.  This mathematical operation is performed point-for-point during the sweep by the network analyzer.  Coupled port return loss is shown in the upper-right window.
