A line of broadband in-phase Wilkinson power dividers from Marki Microwave offers total frequency coverage of 0.4 to 65 GHz with bandwidths to 65:1. The line includes models with SMA, 2.4-mm, or 2.92-mm connectors. As an example, model PD-0140 operates from 1 to 40 GHz with 1.5 dB typical insertion loss (above the nominal 3-dB power split) and 1.50:1 typical VSWR to 40 GHz. The isolation between ports is typically 14 dB from 1.0 to 1.5 GHz and from 38 to 40 GHz, and typically 20 dB from 1.5 to 38.0 GHz. It measures 2.380 x 0.800 x 0.410 in. and is supplied with SMA connectors. Another example, model PD-0R428 works from 0.4 to 26.0 GHz with 2 dB typical insertion loss and 18 dB or better typical isolation between ports.
