Model WMC-0.5-2-6dB-S from Werbel Microwave is a directional coupler that covers 500 MHz to 2 GHz with broadband flat coupling response, high directivity, and excellent return loss performance.  The device covers the upper portion of the UHF band as well as L band in a single unit measuring just 3.60 x 0.60 x 0.38 inches.  The design minimizes reflections and increases accuracy of the measurement.  Mainline insertion loss 1.2dB typical includes coupling factor.  The 6dB coupling ratio gives an approximate 75/25% splitting ratio and may be used as such to distribute signals unequally where required, often to make up for asymmetrical losses elsewhere in a system.  Directivity 23dB typical.  Return loss 23dB typical.  Designed, assembled, and tested in USA.
