MIXER PRODUCTS
MITEQ’s triple-balanced TB0418LW1 mixer series utilizes a dual-quad circuit to provide performance in overlapping
RF and IF frequency ranges. In addition to extremely broadband operation, custom-processed diodes allow for min-
imal variation in conversion loss, extremely high third-order intercept and 1 dB compression points versus input LO
power range. Options for various drive level diodes provide numerous combinations of intercept point and LO level.
This device performs as an up- or downconverter.
