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.

1. All specifications apply when operated at +10 available LO power with 50 Ohm source and load impedance.

2. For IF Frequencies of 5 - 300 MHz and RF of –10 dBm or less.

3. For MDC-169, add 1.0 dB to conversion loss.
