Figure 8. IMD3 for the Combination of LTC6401-26 and LTC2208
of the LTC6401-26 is connected to VCM of the LTC2208
at 1.25V. Alternatively, a single-ended input signal can be
converted to a differential signal via a balun and fed to the
input of the LTC6401-26. Figure 8 summarizes the IMD3
performance of the whole system as shown in Figure 7.
Test Circuits
Due to the fully-differential design of the LTC6401 and
its usefulness in applications with differing characteristic
specications, two test circuits are used to generate the
information in this datasheet. Test Circuit A is DC987B,
a two-port demonstration circuit for the LTC6401 family.
The silkscreen is shown in Figure 9. This circuit includes
input and output transformers (baluns) for single-ended-
to-differential conversion and impedance transformation,
allowing direct hook-up to a 2-port network analyzer.
There are also series resistors at the output to present the
LTC6401 with a 375Ωdifferentialload,optimizingdistortion
performance. Due to the input and output transformers, the
–3dB bandwidth is reduced from 1.6GHz to 1.37GHz.
Test Circuit B uses a 4-port network analyzer to measure
S-parameters and gain/phase response. This removes the
effects of the wideband baluns and associated circuitry,
for a true picture of the >1GHz S-parameters and AC
characteristics.
