APPLICATIONS INFORMATION
Test Circuits
Due to the fully differential design of the LTC6416 and its
usefulness in applications both with and without ADCs,
two test circuits are used to generate the information in
this data sheet. Test circuit A is Demo Board DC1287A,
a two-port demonstration circuit for the LTC6416. The
board layout and the schematic are shown in Figures 6
and 7. This circuit includes input and output 1:1 baluns
for single-ended-to-differential conversion, allowing
direct analysis using a 2-port network analyzer. In this
circuit implementation, there are series resistors at the
output to present the LTC6416 with a 382Ω differential
load, thereby optimizing distortion performance. Including
the 1:1 input and output baluns, the –3dB bandwidth is
approximately 2GHz.
Test circuit B is Demo Circuit DC1257B. It consists of an
LTC6416 driving an LTC2208 ADC. It is intended for use in
conjunction with demo circuit DC890B (computer interface
board) and proprietary Linear Technology evaluation soft-
ware to evaluate the performance of both parts together.
Both the DC1257B board layout and the schematic can
be seen in Figures 8 and 9.
