MICROLAB's TK-28 series 200 W cable loads are intended for wireless applications, when extremely low PIM, passive intermodulation, is required. A typical application is terminating the unused port of a hybrid coupler used to combine different wireless signals. A broad frequency range of 300 – 2700 MHz covers the majority of wireless applications requiring low PIM performance. Air flow over the load is assumed, in order to meet the rated surface temperature.
