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.
