HMC900LP5E Evaluation Kit User Manual

4.1.2  Single-Ended Inputs/Outputs Configuration

Hardware board changes are required to configure the HMC900LP5E Evaluation Board 
for single-ended operation 

4.1.2.1 Single-Ended Input Configuration

To configure the HMC900LP5E Evaluation Board for single-ended input operation, 0 Ω 
resistors R41, R42, R45, R46 need to be removed, and the following components need to 
be populated: 

•  0 Ω resistors, R40, R43, R44, R47, R57, R58

•  10 µF capacitors, C45, C46

•  and two ADT2-1T Baluns (T3 & T4)

Note that the components required for single-ended configuration are not included in the 
HMC900LP5E Evaluation Kit:

Single-ended input configuration of the HMC900LP5E is shown in Figure 4.

4.1.2.2 Single-Ended Output Configuration

To configure the HMC900LP5E Evaluation Board for single-ended output operation, 0 Ω 
resistors R19, R9, R18, R26 need to be removed, and the following components need to 
be populated:

•  0 Ω resistors, R10, R20, R17, R25, R2, R5

•  10 µF capacitors, C44, C43

•  and two ADT2-1T Baluns (T1 & T2)

Note that the components required for single-ended configuration are not included in the 
HMC900LP5E Evaluation Kit:

Single-ended output configuration of the HMC900LP5E is shown in Figure 5.
