The unique design of the termination insensitive mixer (TIM) enables it to apply high reverse voltage to diodes during their ""off"" phase, in the LO cycle. This allows for higher power level performance with minimum distortion. In addition the TIM has internal loads that provide a good match and also absorb mixer generated LO frequency terms. Combined, these features give the mixer its insensitivity to external mismatches, plus superior VSWR.
