4. Hardware Setup
Setup all hardware according to Figure 1.
• Connect USB board to HMC1023LP5E Eval board.
• Connect the USB cable to USB board.
• Apply +5.5 V to TP2 (TP1 is GND) on (HMC1023LP5E) Eval board. Supply current
should be ~230 mA.
• I/Q inputs to J6, J7, J8 and J9.
• I/Q outputs to J1, J2, J3 and J4.
• Common mode voltage (2.5 V typ) is generated directly on the board for the input and
output connections.
4.1 Evaluation Board Configuration
The HMC1023LP5E Evaluation Board schematic shows both differential and single-ended
configurations with components required for single-ended operation labeled ‘depop’.
4.1.1 Default Configuration (Differential Inputs/Outputs)
The HMC1023LP5E Evaluation Board is shipped configured for differential operation by
default. Components required for single-ended operation are specified in the Evaluation
Board schematic, but are not populated. Default (differential) input and output configurations
are shown in Figure 2 and Figure 3 respectively.
