Description
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.
