This water load has the Varian flat flange and a -60 db E-field probe.  As with EM Design’s R284-3.0, this high power load is very useful for converting a circulator into an isolator.  The broad band performance of the load is especially useful for magnetron applications because it absorbs the spurious signals, as well as the desired fundamental, with equal efficiency.

It is an extremely broadband water load that covers almost the entire bandwidth of the WR284 waveguide.  This waterload is optimized at the 2.998 GHz frequency, and can also be optimized at 2.856 GHz.  For optimum performance, we recommend that you install the waterload with an EMD284V gasket seal.
