5 Input and Output Connections
Input signal connections for the ALM2403Q1EVM are provided through the use of the SMA connectors
and test points located at the left of the EVM. The dual output-amplifier connections are provided through
connector J3 and test points located at the right side of the EVM. A simplified diagram of the
ALM2403Q1EVM input and output connections is displayed in
Figure 4 .
NOTE: SMA connectors J2 and J4 are not populated. Resistors R6 and R14 are not populated.
